Deference between Netbooks and Laptops

Recently,the market is fulfilled with small, low-cost netbooks,which are called as mini-laptops and popular by many people.Even the current economy pressures rise and worldwide economy in gloomy condition, why they are so popular as well as laptops? Maybe their merits as follows:

• the shape

First, from the appearance, although it looks very similar like ordinary notebook , it will have a certain difference in screen size and battery. Netbooks are mostly 7-10.2 inch screen, while the average laptops are basically more than 10.2 inch. In addition,netbooks accentuate portability mostly small and thin , while brilliant colors.

• the Configuration and Performance

In a sort of the configuration and performance , netbooks basically used Intel Atom processor, emphasizing low power consumption and long battery life and performance to meet the basic needs of the Internet-based, while the average notebook holds a more robust multimedia performance. In addition ,netbooks have a greater emphasis on the ability of searching internet wireless, hard disk size is not as large as regular notebooks.

• the use

Netbooks are mainly internet-based, they can support making friends online, web surfing, listening to music, view photos, watch streaming media, instant messaging, e-mail, basic network games.Meanwhile, the ordinary laptops, you can install the high-level and complex software, download, store, play CD / DVD,take video conference, open, edit large files and do multi-tasking, as well as the rich experience of more games needed to be installed and the longer last of battery.

• the price

Currently on the market, netbook’s range of price is 1500-3999 yuan, while the traditional notebook is positioned according to the manufacturer and user’s demands, among 3,000 yuan in the ten thousand dollars or even more high.

Because netbooks are designed for ultraportability, they strive for both lower battery weight and longer battery life. Often, lower power consumption has meant reduced performance¡ªa big no-no for traditional laptop marketing. But for netbooks, which strip down the computer¡¯s power needs with lightweight operating systems and software, performance trade-offs aren¡¯t a significant problem. By including energy-efficient components, such as highly efficient processors and solid-state drives, netbooks can make the most of smaller batteries.

laptop li-ion battery separator be more efficient

As international oil prices high,adapter for laptop more and more car drivers to take into account in determining the fuel economy, which directly led to a worldwide market share of hybrid vehicles rose. Expected that by 2012, U.S. sales of hybrid cars will be increased to 100 million. In order to meet the demanding needs of hybrid cars, laptop battery is key components – membranes must be improved, improve energy efficiency, thus providing more power for this vehicle, the courage to deal with the challenges of the world’s energy shortages.

The important role of the diaphragm is small

Due to the high energy density lithium batteries(xps m1330 battery,latitude d830 battery), long cycle life, light weight, small size and other characteristics, but also has a safe, reliable and can quickly charge and discharge, etc., to become the new power technology in recent years, the research hotspot in the field of high-energy and high-power reserved popular. In the lithium battery structure, the inner membrane is a key component of the. Diaphragm made of plastic film is able to isolate the battery positive and negative, in order to prevent short circuit; also be in the battery overheating, through closed-cell function to block cell in the current conduction.

Chemical’s chief polymer scientist said Bai Peide, lithium battery separator battery costs account for the cost of a / 3. Membrane determines the performance of the batteries(gd761,kd476) interface structure, resistance and so on, a direct impact on the battery capacity, cycle performance, and security features such as, high-performance membrane in improving overall performance of the battery has an important role. At present 60% to 70% of the membrane market, mainly in wet bi-oriented process, because the wet, bi-lateral vertical stretch more evenly balanced. It is mainly used for high-end diaphragm wet, dry method has been applied in the low-end products.

A huge global market volume

Global Li-ion battery production in the past 15 to 17 years has maintained an average of 10% to 20% growth rate from 2001 onwards, the average annual growth rate was as high as 40%. Rapidly growing lithium battery market, in addition to watches, and other one-time button-type batteries,inspiron b120 battery and inspiron b130 battery, as well as secondary rechargeable lithium-ion batteries. In addition to the current lithium ion batteries are widely used in daily well-known mobile phones, notebook computers and MP3 and other digital electronic products, in electric cars, electric bicycles and some other high-power batteries have also been started.

At present, countries are scrambling to develop electric cars, hybrid cars will need batteries to provide power, as a pure electric vehicles matching power supply, lithium-ion power supply for its outstanding performance, is becoming the core of the power type. As the hybrid line with today’s national energy development needs of a large environmental protection, consumption growth must be greater than 20%. Reason to believe that lithium batteries will eventually occupy the dominant position of secondary battery market, as its key components, the lithium battery separator huge market capacity.

Personality development to improve energy efficiency

Battery separator is mainly the development of lithium-ion batteries(inspiron e1705 battery,inspiron e1505 battery) with the evolving needs and continue to develop, from the volume point of view, lithium-ion batteries are moving in the small and large two distinct direction. In some, such as mobile phones, digital cameras and other electronic products, in order to meet the beautiful, easy to carry the demand on the battery batteries battery factory has been very small. In pursuit of high energy density, in the small size of the electrode can accommodate more material, the battery manufacturers want to divide the thickness of the thinner the better. Smaller diaphragm is a challenge because of the need to do a thin membrane, but to be able to maintain the original battery capacity, cycle performance, and security features, and greater power, the design easier.

By contrast, in electric bicycles, electric vehicles and electric tools used by power batteries, in order to obtain high-capacity, high-power, usually a battery need to use dozens or even hundreds of batteries to concatenation. Because lithium batteries have the potential explosion hazard, the safety diaphragm is important. Due to become bigger and bigger, technically demanding more efficient and reduce greenhouse gas emissions, power stronger.

Bai Peide convinced, lithium battery separator according to the different needs of different customers to develop targeted products, which divide the future trends. Although the divide is mainly single-market products, but Exxon Mobil has been able to put different materials on different membrane layers, each layer with different formulations vgp-bps2c battery of solvents and raw materials to multi-layer co-extruded to produce hot-melt thickness and diameter of hair, similar to divide and thus produce different properties of products, Bai Peide predict the future trend of multi-layer membrane is also obvious.

Still need to speed up the development of China

According to the Irish market research firm recently issued a lithium battery market forecasts show that China’s current production of lithium batteries as the world’s largest. In the global lithium battery production, the Chinese mainland accounted for 16.9%, China Taiwan region accounted for 6.9%. According to China’s Power Industry Association of Chemistry and Physics, Statistics, 2007 China Li-ion rechargeable battery production reached 1 billion.Affected by China’s lithium-ion battery separator market-oriented development has also begun to take shape, now showing a very good momentum of development. In accordance with the battery output of 1 billion is estimated that consumption of each diaphragm 300 million ~ 500 million square meters between the market value of 10 billion to 1.5 billion.

However, China’s research and development of lithium-ion battery separator got a late start, lithium-ion thinkpad t60 battery separator still mainly rely on imports, leading to the market price remains high. At present, only Japan, the United States and a few countries have a lithium battery separator production technology and the corresponding large-scale industry. China’s domestic market, over 80% of diaphragm were the United States, Japan and the occupation of imported products, domestic divide is mainly in the middle and low-end markets.

The future, China needs to strengthen the industry, academia, research inputs, to develop research achievements with independent intellectual property rights, breaking the Japanes and American enterprises in the membrane industry, technological monopoly; the other hand, enterprises and research institutes should strengthen cooperation, speed up the results The industrialization process of transformation.

China lithium batteries lose a fight to defend a patent bureau

China lithium batteries lose a fight to defend a patent bureau

In the first half of this year, this newspaper since 3114, the four successive interest of the University of Texas and its commercial mandate Hydro Quebec, Canada, Phostech alleges that the U.S. battery maker A123 (GEM), Inc., Vaillant (Valence) Company Infringement lithium ion phosphate patent dispute. This series of reports have caused widespread concern outside the industry. Today, lithium ion phosphate laptop batteries on the topic of the patent once again affects the electric car industry’s nerves, but the protagonist of the incident replaced by China.

On lithium ion phosphate in North America, playing a flurry of patent lawsuits when a lithium ion phosphate battery patents to defend the war broke out in China. DVD patent pool

To avoid recurrence of this tragedy, our country more than the battery(GD761, KD476 ) companies and research institutions are positive actions, to collect evidence to prove that Hydro Quebec and the French research center in China last year, the application of phosphorus acid, lithium ion-layering carbon technology patents (now an exclusive license to the Canadian Phostech company) is invalid. However, the present situation, the Chinese side want to win, extremely difficult.
The success of foreign companies in China apply for patents

layering of carbon this year, China’s electric cars and motive power batteries forum is particularly high. In almost every forum, can see the shadow of Canada Phostech company representatives.

Not long ago, the fourth South China Lithium Power (International) high-level Technical Forum held in Shenzhen. Made a special trip from Canada came to participate in the forum Phostech Rice, CEO? Toston smiling. After the introduction of products and technology, Toston answered live audience on the patent question. He said: “In the United States, the Tribunal intends to recess for some time to continue to hear from companies such as our A123 lithium ion phosphate battery patent dispute. Last December, the European Patent Office rejected the Phostech the company’s lithium ion phosphate battery patent application(Dell inspiron E1505 battery ,inspiron 1501 battery) . We intend to continue to apply for patents, is expected to be approved in 2010. In addition, in Japan, we are also actively apply for a patent. ”

Toston Phostech talked about companies in the United States, Japan and Europe application for a patent case, but did not mention China, and I wonder if the wish to avoid. According to report, in 1999, the French scientific research center, Professor Michael? Oman and Germany invented the carbon-layering technology, solves the conductivity of lithium ion phosphate materials, poor problem. Subsequently, from Hydro Quebec and the French Scientific Research Center have applied for the patent. In 2008, the two institutions in the Chinese patent application is approved, the patent has been the exclusive right to use license to the Canadian Phostech company. Seize the high ground in the patent

after, Phostech actively explore the Chinese market. Currently, the company has opened an office in Shanghai. At the same time, its high-level frequent appearances in China, and actively promote the company’s lithium ion phosphate batteries and materials.

two patents can not by pass

Chinese Academy of Engineering, Li-Quan Chen told reporters, in the lithium ion phosphate batteries,dell battery inspiron e1505 and material field, there are two core technology patents can not be bypass, one of which is the layering of carbon technology patents, and the other is the carbon-thermal reduction technology patents. The former has applications in China, the Canadian company has the exclusive right to use Phostech; the latter owned by the United States Viagra can be company, has yet to apply for a patent in China. However, Viagra can be company has set up two companies in Suzhou — Vaillant Technology Co., Ltd., Takeyasu Energy Limited, are responsible for the production of lithium ion phosphate materials, and battery production(dell GD761, KD476). In order to seize the Chinese market, Viagra can be company does not rule out the patent on the trivial.

Academician Li-Quan Chen also told this reporter in a surprising thing: It turned out that Viagra can be company owned by the carbon thermal reduction technology patents, is entirely his students — Dong masterpiece.

2000, the Dong switched from a Canadian company to enter the United States Vaillant, serving as a senior research fellow. Prior to that, he has been the French National Research Center for Condensed Matter Physics Institute of Chemistry of Bordeaux and received a doctorate and post-doctoral study in the United States. In Vaillant’s work, Dong fully demonstrated the Chinese people industrious, intelligent character in just six years, he helped Vaillant companies in 28 countries around the world applied for the patent materials, lithium ion phosphate (Dong is the inventor , the property Vaillant companies).

However, things are unpredictable Dong was perhaps never imagined that today, these patents would become the Chinese battery (dell xps m1330 battery,xps m1730 battery)enterprises to enter the field of lithium ion phosphate battery barrier.

“At that time, I can think of their own materials, lithium ion phosphate formulations and preparation methods are written out and apply for a patent. Some of the patent, Viagra can be company already has a corresponding time technology, and others are under development, there are simply not begun to study. This series of patents is very tight, almost covering the manufacturing aspects of lithium ion phosphate battery is indeed hard to break. “talking about past events, Dong so right , told reporters.

want the patent is invalid, the Chinese side little chance of toppling

“in the lithium ion phosphate batteries and materials, China has absolutely can not be called art. There are few enterprises that Patent no problem, it is nonsense, and there are many complex issues to be resolved. If we say that, for the University of Texas and the A123 between other organizations such as lithium ion phosphate patent dispute case, we are somewhat indifferent manner of taste, then this a company in China with access to packet Phostech deposited carbon technology patents, as well as companies such as Viagra can seize the Chinese market to accelerate the pace of the patent problem has become very realistic placed in front of us, not be evaded. “a company official said the battery.

Is aware of this, these batteries(dell inspiron b120 battery,inspiron b130 battery) before businesses and relevant research institutions together to gather evidence, look forward to tear down barriers to multinational patents.

State Intellectual Property Office a staff surnamed Wang told reporters, “Patent Law” Article 22 clearly provides that a patent application at least have novelty, creativity and practicality, and no other substantive issues, in order to be authorized. By the same token, if you want the patent invalid, the State Intellectual Property Office shall review committee to pursue the invalid request has been authorized by the patent to prove there is no novelty, inventiveness or usefulness. If rejected, you need to bring an action through the legal channels to resolve.

The staff member also said that the best means of proof is to find a one or more previously public documents, and to compare the patent claims, xps m1330 battery,if the overlap, you can prove that the patent the lack of novelty. Corporate sources, and now they have found an open literature, but the arguments are not particularly strong. Once the proceedings, the odds are not great.

Chinese Academy of Sciences Institute of Physics, doctoral tutor Huang Xue-Jie said, after the U.S. Japan’s NTT paid 30 million yuan (equivalent to RMB) settlement, the only solution of the lithium ion phosphate material patent disputes. Many enterprises in Taiwan is to spend money to buy other companies to Phostech the right to use the patent. “If in the end, China and Japan, companies have to embark on the road to spend money on patent licensing, which is China’s ion phosphate lithium battery manufacturers would be a bad news, but also a sad thing.”

Dell Inspiron B120 and Inspiron 1300

The Inspiron B120 is currently the most inexpensive Dell laptop that can be purchased. It is sold under Dell’s Home division and an identical Inspiron 1300 is sold under the Business division. One may think that the B120 could not possibly have much to offer at such a low price, but you will be surprised at how much horsepower this budget notebook has.

Solar Power From Your Windows

Solar Power From Your Windows

As a member of UA professor Neal R. Armstrong’s research group, Placencia conducts research aimed at creating a thin, flexible organic solar cell that could power a tent or keep a car charged between trips to work and back home again.

He’s passionate about renewable energy and says it’s a waste that so little solar has been incorporated into society. “I have a little flat panel that I walk around with,” Placencia said. “I usually put that on my backpack, and I charge my cell phone when I’m walking to school.”

The sun is clean and free. “Here it is,” he said. “Why not use it?”

Across the University, professors, researchers, students and others involved in policy planning and economic analysis are working to make that question moot. In a region noted for abundant sunlight, they are chipping away at problems like how to employ solar at the utility-generating plant level, how to harness it to charge the newly indispensable products of the day – cell phones battery, MP3 players battery, laptop battery– what to do at night and when clouds halt the energy giveaway from the sky.

The research proceeds in labs amid state-of-the-art equipment funded by multimillion-dollar federal grants. It’s the product of students’ hunches and long careers spent unlocking the mysteries of science. Along the way, students are being immersed in a nascent industry that many hope will be the economic engine of the next decade.

“Looking at renewable energy is a perfect place to emphasize that we don’t know where the next breakthrough is going to be,” said Leslie P. Tolbert, UA vice president for research, graduate studies and economic development. “Somewhere in a lab someplace, there’s somebody figuring out a whole new way to capture sunlight. In fact, there are many people doing that. And even they are depending on knowing that there is, behind them, a cadre of basic science researchers producing new information that will feed their thoughts.”

Armstrong, a professor of chemistry and optical sciences at the UA, occasionally teaches freshman chemistry. He decided one day near the end of the semester to try to make the material even more relevant. “I said to myself, well, lithium ion batteries(inspiron b120 battery,inspiron b130 battery) in my cell phone, in my iPod,” – his daughter had given him one – “I wonder how much coal we burn to charge those guys up at the end of the day. Because that’s one of the big drivers for portable power, to get all this stuff off the grid.” After making some very conservative calculations, he arrived at an answer, which he shared with the class: “You burn about a quarter of a pound of coal per charge of your lithium ion battery, and you generate about half a pound of CO2 per charge, per battery, per day …. The room got really quiet.”

“It really is chilling,” Armstrong said. “You start doing the math and thinking about the number of consumer electronic devices that you and I have added to our lives in the last decade that I charge up typically once every night – my laptop computer and my cell phone. Then you start thinking about, ‘What if I do buy an electric car, and I come home at night and plug that sucker in,’ and you do the same thing. We’ll shut this grid down in no time.”

In April, the U.S. Department of Energy announced it was funding Armstrong’s Center for Interface Science as one of 46 Energy Frontier Research Centers. The mission of these centers, which will receive $2 million to $5 million a year for five years, is “to address current fundamental scientific roadblocks to clean energy and energy security,” according to the DOE.

Ever since Armstrong was a graduate student during the first Arab oil embargo in 1973, he’s experienced a succession of government distress calls over energy. One such emergency led him to discover the work of Heinz Gerischer and Frank Willig in Germany. They had figured out how to adsorb dye molecules to the surface of oxides and split water with light from the sun. “I thought, ‘That’s it. That’s what I’m going to do my career on.’”

He moved to the UA in 1978, attracted by a program in photo-thermal solar energy conversion. In the 1980s, with gas cheap and plentiful again, solar went back on the back burner.

The next call came about four years ago. “DOE was beginning to sense that the tides were about to shift again, big-time,” Armstrong said. “And they were really concerned that they didn’t know what to do – how to present this to Congress in a way that would lead to new funding and which would have a rationale associated with it so that by the middle of this century we had someplace to go.”

Armstrong realized it was time to come back to the problem that he wanted to work on 30 years before. “This time, we were really well-equipped,” he said. “We’ve learned how to image molecules at the molecular level, we’ve learned how to measure energies of incredibly thin films, we’ve learned how to make devices, we’ve collaborated with physicists and material sciences and that sort of thing, we’ve done a lot of interesting other stuff and I suddenly realized I could bring it all back together here.”

In his office, he displays a sample of his work: a 1-inch square of glass on which is deposited a thin film of indium tin oxide, a conducting transparent oxide commonly found in display technologies like computer screens. On top of that is a thin film of organic dyes. The last layer is an aluminum electrode.Solar power will be used laptop,give battery give more energy,power dell b120 battery,hd438 , kd186 battery .

“You’d have a roll of plastic with these cells laid out on it,” he explained. “The idea is for you to go to Target or something like that and buy this roll of plastic and roll it out. It’s got two wires connected to it, and you plug in your battery or your laptop and charge it up.”

“The grand total in terms of the thickness is about 400 nanometers, which is one ten-thousandth the thickness of a human hair. And yet, shine a light on it and you get electricity out of it. Now we’d like it to be a bit thicker. We have to keep them thin in order to get all of the electrical charge out of the device. But if you think about this as a sandwich structure, we’ve made this incredibly thin sandwich and then each of the layers in contact with each other have to be just right in terms of the chemical composition, the orientation of the molecules, how well they adhere to each of the underlying surfaces. And if I go in and change just one molecule layer, the composition – that’s at the level of 1 nanometer in thickness – I can take a good device and turn it into a bad device; I can take a bad device and turn it into a good device. That’s the kind of level of control that we need. And we don’t fully understand it.”

But the equipment available now – optical microscopes capable of imaging individual molecules and revealing their electrical properties and spatial orientation – are helping his team understand. His goal is to figure out how to have the molecules arrange themselves – every time – in a way to produce lots of electricity. “They have to all line up like little soldiers,” he said.

“We have to give you a technology that is going to look like an ink, like a blue ink, that you can spray down on one of these surfaces and the molecules at the nanometer level are going to say, ‘OK, we’re going to get organized this way,’ and in doing so, when I put that top electrode on and shine a light, I’ll get lots and lots of electricity out of there,” Armstrong said.

A high vacuum photoelectron spectrometer allows them to build each molecular layer,laptop battery–latitude d830 battery,latitude d620 battery . moving it within the vacuum to study it, and then continue with another molecular layer. Other tools, like a silicon microtip, which looks like a tiny phonograph needle, can be positioned to +/- 0.01 nanometers. “Well inside the diameter of a molecule,” he said. Bouncing a laser off the back of the tip yields an image. Passing current through the tip, they can map the electrical properties of molecules. All this can help them build a template to create the ideal array of the molecule assemblies.

Erin Ratcliff joined the team as a postdoctoral electrochemist with a doctorate from Iowa State. “My background wasn’t in solar cells at all,” she said. “I had to come here and had to learn everything, where grad students get it from Day One at the UA.”

She spoke of the business school curve, resembling a hockey stick, when progress begins to accelerate rapidly. “We’re right at the magic moment when the hockey stick starts to take off, when you go from flat to hockey stick. We’re right there. It’s exciting to read the literature and hope that, yes, we will take off. It will be exciting to look back and say ‘I was there for that.’”

Battery maintenance and correct using

Battery maintenance and correct using

Laptop battery can be said that the most important source of inspiration. No batteries to provide energy, you can not complete the special requirements of mobile office. Then we can at best laptop in the hands of a mobile PC Bale. The laptop battery maintenance and use of skills has become a headache for most consumers the best thing.

A. In the purchase laptop battery after more than three consecutive 12-hour continuous charging, to prevent “memory effect”

Memory effect refers to the battery to withstand a long time after a particular work cycle, automatically keep this particular trend. Therefore, saying that if every time the battery(dell inspiron e1505 battery) charge only 50% of the time began to use, then the subsequent memory effect the battery will be the next times when the charge can only charge to 50% of the time on the “can not be recharged inside of.”

As the manufacturing process of the gradual improvement of lithium ion batteries,gd761,kd476,td347 etc. constant current charging method for deep-charging time of its control in 4 hours,Laptop battery is dead on the charge, every two weeks or a month’s time resting, will conduct a depth of laptop battery discharge, is to use battery-powered, no electricity and then used directly on the computer automatically shut down on it. However, the number of times the depth of discharge should not be too frequent.

B, using the AC adapter when the battery should be removed first in order to avoid the battery “full blast”

Currently on the market lithium-ion batteries used in laptops can complete 300 to 600 times of charging and discharging process, we can calculate what their own, and now on the market Centrino models of battery life time is normally more than the official data for 5-6 hours,inspiron b120 battery,inspiron b130 battery. Ben 4 models the battery usage time of 3 hours,Friends using the AC adapter when the battery get down and worried about is that if your are more left inside the battery power, plug in the AC adapter, the results of the results began to charge the battery caused by their own waste is a “charge number of times. “In fact, this worry is unnecessary, because the laptop battery power within the state certainly can not be hundred percent, so when using the AC adapter will definitely be completed charging.Notebook computers are designed with battery protection measures, such as IBM’s notebook only in the capacity less than 95% of the time will be charged.

The chance of battery explosion is small . However, May occur, lithium-ion batteries which are lithium batteries, a control circuit between them and the management board to complete the charge and discharge, if the control circuit to lose some of the features of the sensitivity of the original or direct failure, you can not be effectively control the current, internal batteries temperatures cause the explosion. Or the dell laptop battery short-circuit inside the batteries will explode.

C, the battery usage time did not meet the official standards, definitely the battery problem

If a friend who has reached the battery standby time less than “official battery using the standard,” then we can still be extended through a number of ways:

1,25 ℃ ~ 40 ℃ using a standard external environment, the use of lithium-ion batteries can reach the best condition, if the temperature is too high, not only run the notebook computer itself to slow down or even crash, but the battery in such an environment is also under the will affect its efficiency. So, as far as possible under the indoor environment using a laptop.

2, the less frequently used device is disabled. Usually when using the battery-powered best to temporarily disable the swap the unwanted interfaces, such as wireless network card, printer port, infrared port, 1394 Firewire port, etc., or would waste a lot of battery power,inspiron E1505 battery , the specific method is in the ” Control Panel “-” System “-” hardware “-” Device Manager “to find their own want to disable the device, and then click on” disabled “can be, and need to use the time to be” enabled devices “, is very simple. After disabling the use of results have been very obvious, you can save a lot of power.

3, reduce internal power consumption of devices. More and more CPU-frequency, high-speed hard drives will bring a lot of energy consumption and increased heat dissipation. Therefore, no special requirement, then the best use within the system or a third-party software to control the drive speed, do not open too many windows and programs in order to avoid CPU overload of work, so not only can reduce the battery power consumption, another can also reduce the bulk heat, in the “autumn tiger” there is the season, this is still a little benefit.

D, In starting laptop to charge the battery is very harmful

In the notebook, the previous design of some models is that if the use of battery-powered, then even if the plug AC adapter, books, or the use of battery-powered, dell gd761,kd476 battery.which means “can not be recharged into the” phenomenon of today’s notebook computers are not so The design of the dangerous, and when the plug when the AC adapter immediately shifted to an external power supply and began to charge the battery.
