TOKYO –Sony has provided greater detail about a battery manufacturing problem that is expected to see the replacement of up to 9.6 million laptop computer battery packs.

What Went Wrong?
The problem was first acknowledged in August when Dell issued a recall for 4.1 million batteries and until now had been explained as metallic particles that got into the battery during the manufacturing progress. Today Sony expanded on this and said the particles, believed to be nickel, likely got into the battery during two stages in production: when a groove was created in the battery case and when the electrolyte was poured into the cell.

But that alone wouldn’t be enough to cause the fires that have been reported by Sony VGP-BPL2 owners. For that to happen Sony believes that the particles would have to fall into a small triangular gap in the cell body right at the point where the cathode ends between two layers of spacer material. Then, depending on system configuration, the conditions could be right for a fire to start in the battery.

“The probability of this occurrence very much depends on system configuration,” said Takashi Enami, senior general manager of the energy business group at Sony. He said size and shape of the battery pack and the charging configuration could all increase the risk but he wouldn’t offer any specific information citing confidentiality agreements between Sony and its customers.

Replacement Program Details
As a result of the problems 6.1 million Sony VGP-BPS8 batteries have been recalled by Dell and Apple Computer. An additional 3.5 million batteries are covered by a Sony-led replacement program that offers new batteries to laptop users who are worried about the safety of their system. Last week Sony said it anticipates costs of $429 million as a result of the battery problems.

The replacement program covers two types of cells used in battery packs, a 2.4Ah (ampere hour) and 2.6Ah model, and information on the affected battery packs and laptop PC models sold in the U.S. can be obtained from the U.S. Consumer Product Safety Commission.

Sony considered the Sony VGP-BPS8A  battery replacement after a Lenovo-made laptop caught fire at Los Angeles International Airport, said Yutaka Nakagawa, executive deputy president of Sony and head of its semiconductor and component group. That incident is still under investigation and as only two of the six cells inside the battery pack remain it’s difficult to pinpoint the exact cause, he said.

“In preparing for the program we have been in discussion with the CPSC and the PC manufacturers, which required time, and that is why the announcement is being made today,” said Nakagawa.

Sony Will Outsource Some Replacements
The replacement batteries won’t all come from Sony because it doesn’t have the manufacturing capacity to produce them all in the time required, said Nakagawa. As a result Sony will source some cells from rival companies. Nakagawa said as a result there is a general possibility that Sony might not win back all the business it had before the Sony VGP-BPS9 battery problems occurred. Its success or failure in keeping business very much depends on how well Sony does to persuade customers that the problems are behind it, he said.

Additionally Sony also increased the number of its own battery packs eligible for the replacement program. Last week it said 60,000 batteries used in PCs in Japan and China would be replaced and today increased this to 250,000 batteries worldwide.

Battery making start-up Boston Power is more than tripling production of its Sonata laptop battery, a device that offers faster charging and longer life than conventional lithium-ion batteries, it is due to announce Thursday.

Boston Power has also struck a manufacturing partnership with Taiwan’s GP Batteries, which will begin making the cells to supplement current production at China’s HYB Battery. GP will produce around 1 million cells per month, said Christina Lampe-Onnerud, founder and CEO of Boston Power. HYB currently produces between one third and one half that amount, she said.

The Sonata PC764 battery was a hit when it was unveiled at the Demo 2007 conference in January 2007 because, according to Boston-Power, it gets over some of the main frustrations laptop users have with their battery packs. Namely it can be charged to 80 percent of total capacity in 30 minutes so even on a short lay-over a meaningful amount of power can be recharged into the battery and it should also last the average three years that people keep their laptops without a noticeable degradation in performance.

In light of a series of high-profile problems and recalls of lithium-ion batteries, Boston-Power is also pushing safety. It says its Sonata battery uses less reactive chemicals and has a series of protective controls that make it safer than competing batteries.

With the extra production, Boston-Power will be looking to pick up customers for the Sonata Latitude D620 battery. It has already been working closely with Hewlett-Packard.

“We are delighted with the response from the market. Interest is really, really large” said Lampe-Onnerud. “We have worked with top-tier notebook makers for several years and they remain extremely engaged. Many have already qualified our system but we’re a small company so we have to be selective about who we work with.”

Boston-Power has also closed a third round of financing for US$45 million, which it will announce Thursday. The round, led by Oak Investment Partners, also included additional money from existing investors Venrock Associates, C1295,Granite Global Ventures and Gabriel Venture Partners. The latest investment brings to US$68 million the total amount of funds raised by Boston-Power.

Apple is looking at ways TV, magazine and newspaper content can be presented differently on its upcoming tablet device, according to a report published in the Wall Street Journal on Wednesday.

The company is also targeting the tablet as a gaming device, for which Apple is working with video-game publisher Electronic Arts, according to the report, which quoted people familiar with the situation.

Apple reportedly is talking to many service providers to deliver content to the device. For magazine content, Apple is talking with companies including The New York Times, Conde Nast Publications and News Corp., the apple a1008 battery report said. Apple is also negotiating with CBS and Walt Disney to deliver monthly TV subscription services.

Apple is reportedly also talking to HarperCollins Publishers to sell electronic books for the tablet. As part of the deal, HarperCollins will set its own price for the e-books, from which Apple will get a cut. Apple’s purchase of streaming music provider Lala.com in December has also been linked to the tablet.

Though Apple hasn’t confirmed the device, the company has sent out invitations for a Jan. 27 launch event where the tablet is expected to be launched. The device is said to be a larger version of the iPhone with a touch screen sized about 10 inches to 11 inches and a virtual keyboard.

Kai-Fu Lee, a former Apple employee and previously the head of Google in China, apple a1012 battery,recently blogged that the tablet would come with 3D graphics and a price tag below US$1,000.

Besides in the choose and buy when should see clear batteries size besides, in at ordinary times in using, we also want understanding how to maintain batteries!

a netizen sends a message to say today, his IBM because this machine did not maintain goodly batteries, brought about to use the batteries that does not arrive one year to already drew near finally discard as useless. The most interesting nevertheless still be from the back, this netizen continues say, he of unwilling to give up sought all sorts of meanses that save batteries, let this batteries eventually ” renascent ” .

Be what method after all, I am described probably. Go up from above all get off batteries, seek a piece of paper again, will already ” death ” batteries has been wrapped. Look for the plastic bag with one proper size again, the toshiba pa3191u-1brs , toshiba pa3166u-1brs  that has included paper is put in, give off the redundant air inside the pocket, with mouth of bag of pitch of line or oak adhesive plaster.

Open the entrance door of freezer freezer compartment next, will this ” classic ” inside the refrigerant case that puts 5 degrees. After closing, patient ground awaits 72 hours, namely 3 days ah. As to the utility of newspaper, it is to absorb redundant moisture, polybag is airtight save in order to prevent external moisture is entered.

After 3 days, take out battery, take out polybag and newspaper, 48 hours are placed below room temperature namely the 2 machine on the Queen of heaven charge. The miracle appeared later, batteries can hold to 1 hour 18 minutes 0. Very long time has been for the toshiba pa3331u-1brs, toshiba pa3399u-1brs that dies to drawing near together.

Do not cross this ” cheat cadaver ” the process is really false after all, we still cannot decide. To the folk prescription of this kind of folk, there still is a lot of on the net, the friends that have fun at conditionally can have a try, ah.

Be here nevertheless or teach everybody a few maintain correctly the method of batteries. Main component is the following at 4 o’clock:

The first, avoid to discharge completely, and often charge to lithium  toshiba pa3250u-1brs , toshiba pa3356u-1brs. And charging at will repeatedly is very small to the injury of lithium batteries, almost negligible not plan.

One of the most important catalysts in the modern chemical industry is a troublemaker. The building blocks of zeolite ZSM-5 crystals, which are a sort of Swiss cheese with molecular size holes, are not joined together perfectly. The materials that have to pass through the crystals therefore often get stuck and don’t react well. Dutch researcher Marianne Kox discovered the deviations in the miniscule but indispensable particles.

Nearly all medicines, fuels and other chemical products come into contact with catalysts at some stage of their ‘lives’. These help to convert one material, for instance crude oil, into another, such as petrol. Take a good look around and you can see the evidence of the hard work done by these catalyst particles everywhere. Marianne Kox studied one of the most important catalysts, zeolite ZSM-5 crystals. These particles look like pieces of Swiss cheese with miniscule channels through which the material that has to be converted must pass. But it seems some of the holes do not want to cooperate leading to differences within one individual catalyst particle.

‘Big Brother’ of catalysis

Like a real ‘Big Brother’, Marianne Kox spied on the zeolites with a combination of different micro-spectroscopic techniques. By doing so, she managed to study the zeolite particles in a space- and time-resolved manner, for example the interior of the catalyst in 3D. She discovered why some of the zeolite crystals were not behaving properly, and how their behaviour differed from one position in the crystal to another.

Depending on the shape of the crystals — for example a boat shape or even the shape of a coffin — the channels inside a zeolite crystal didn’t seem to run properly, and they could get blocked. This was caused by the building blocks that make up the zeolite crystals not fitting together properly. As a result of this the catalyst did not function as well as it could. Thanks to the unique combination of techniques applied by Marianne Kox, individual catalyst particles and their working principles can be studied in more detail, making improvement of the catalyst possible.

Marianne Kox’s research is part of the Vici project run by Bert Weckhuysen. The December 2009 issue of Nature Materials contained the article Morphology-dependent zeolite intergrowth structures leading to distinct internal and outer-surface molecular diffusion barriers, about this research, to which PhD researcher Lukasz Karwacki also contributed.dell inspiron b130 battery,dell inspiron e1405 battery,dell inspiron e1505 battery,dell inspiron e1705 battery,dell latitude d410 battery,dell latitude d420 battery,dell latitude d430 battery.

Simply coating a sheet of paper with ink made of carbon nanotubes and silver nanowires makes a highly conductive storage device, said Yi Cui, assistant professor of materials science and engineering.

“Society really needs a low-cost, high-performance energy storage device, such as batteries and simple supercapacitors,” he said.

Like batteries, capacitors hold an electric charge, but for a shorter period of time. However, capacitors can store and discharge electricity much more rapidly than a battery.

Cui’s work is reported in the paper “Highly Conductive Paper for Energy Storage Devices,” published online in the Proceedings of the National Academy of Sciences.

“These nanomaterials are special,” Cui said. “They’re a one-dimensional structure with very small diameters.” The small diameter helps the nanomaterial ink stick strongly to the fibrous paper, making the dell laptop battery and supercapacitor very durable. The paper supercapacitor may last through 40,000 charge-discharge cycles — at least an order of magnitude more than lithium batteries. The nanomaterials also make ideal conductors because they move electricity along much more efficiently than ordinary conductors, Cui said.

Bing Hu, a post-doctoral fellow, prepares a small square of ordinary paper to with an ink that will deposit nanotubes on the surface that can then be charged with energy to create a battery.

Cui had previously created nanomaterial energy storage devices using plastics. His new research shows that a paper dell inspiron 6000 battery is more durable because the ink adheres more strongly to paper (answering the question, “Paper or plastic?”). What’s more, you can crumple or fold the paper battery, or even soak it in acidic or basic solutions, and the performance does not degrade. “We just haven’t tested what happens when you burn it,” he said.

The flexibility of paper allows for many clever applications. “If I want to paint my wall with a conducting energy storage device,” Cui said, “I can use a brush.” In his lab, he demonstrated the dell inspiron 630m battery to a visitor by connecting it to an LED (light-emitting diode), which glowed brightly.

A paper supercapacitor may be especially useful for applications like electric or hybrid cars, which depend on the quick transfer of electricity. The paper supercapacitor’s high surface-to-volume ratio gives it an advantage.

“This technology has potential to be commercialized within a short time,” said Peidong Yang, professor of chemistry at the University of California-Berkeley. “I don’t think it will be limited to just energy storage devices,” he said. “This is potentially a very nice, low-cost, flexible dell inspiron 6400 battery  electrode for any electrical device.”

Cui predicts the biggest impact may be in large-scale storage of electricity on the distribution grid. Excess electricity generated at night, for example, could be saved for peak-use periods during the day. Wind farms and solar energy systems also may require storage.

“The most important part of this paper is how a simple thing in daily life — paper — can be used as a substrate to make functional conductive electrodes by a simple process,” Yang said. “It’s nanotechnology related to daily life, essentially.”

Cui’s research team includes postdoctoral scholars Liangbing Hu and JangWook Choi, dell inspiron 640m battery,and graduate student Yuan Yang.

AP minus 45 degrees Celsius in the arctic conditions, can be easy to fire from car? Spare battery is also strong and do a year? Battery acid corrosion can be no excess equipment?
The near-dream for the demanding battery now become a reality. “Starter-type sodium high-energy batteries scientific and technological achievements” recently appraised by experts in Harbin. Chinese Academy of Engineering, DU Shan-yi, and other experts believe that the technology break the battery “friction failure” of the global problem, reached the international advanced level.

Experts have found that the traditional acer laptop battery “internal resistance” and “within the discharge” not only unnecessary to drain the energy, but also lead to side effects such as sulfuric acid spill. Thus the invention of “salt and high-conductivity electrolyte” and “high capacity positive and negative electrode active material endurance formula and production method” two patented technology.

After testing, the new battery capacity is not only higher than the ordinary type more than 15% more conducive to high-current discharge. Starting vehicle, sparking a row of traditional products are generally about 15 times will be failure, while the new acer aspire 5560 series battery,acer aspire 5920 battery,acer aspire 5520 battery has up to 80 times or more. Of Heilongjiang in China’s far north side of the cold polar experiments show that the average long vehicle parking at minus 40 degrees Celsius outside, still be successful ignition.

An atmosphere of air filled floor, with the Department of State letter to the ministries of industry to develop a “pure electric passenger vehicles technical conditions”, “Electric Vehicle Power Battery Size” and other new energy vehicles will be national standards introduced in 2010, the domestic Dozens of cars began to secretly wrestling enterprises the right to speak the national standard-setting, the focus is focused on the plug-in and replace the battery standards.  

However, the pure electric cars are also latent heat behind it a waste of resources, duplication of the building shell. According to incomplete statistics, the domestic electric car project launched the car up to more than 100 enterprises, in addition to well-known state-owned and private car companies, and even a lot of cars without the  production of qualified agricultural companies have also launched electric car project.  

“Appearance of prosperity, in fact it is very confusing. Its very nature, or in order to compete for business standards and strive for greater interests.” A car company executives told reporters. 

Influx of electric cars  

In 2009 the last one month, the domestic automobile battery market prices have almost become a car show planning stage for electric vehicles. December 7, 2009, the Copenhagen climate conference the day before the opening of Changan Automobile announced that its first electric car BenBen MINI off the assembly line. “This car has zero emissions, the second half of 2010 volume production can be truly non-polluting.” Changan Group President to remain flat, said Xu. 

In mid-month, the Shanghai Automotive’s announcement that the company decided to cooperate with A123 Systems Hong Kong Limited was established a vehicle battery power system joint venture to jointly develop, manufacture and sales of vehicle battery power system. Zhejiang public Motors also Putian New Energy Power Co., CNOOC signed a strategic cooperation agreement, both sides will be in a pure electric vehicles to carry out strategic cooperation in a pure electric car to accelerate industrialization and commercialization process. 

December 26, 2009, Haima Motor is in its ground-breaking ceremony in Zhengzhou plant on display at a variety of hybrid and electric cars. 28, Beiqi officially released its first “Beijing” brand electric cars BE701, which vehicles will be low-volume production this year. On the same day, from BYD electric vehicle partners, China Southern Power Grid invested in the construction of the first two electric car charging stations and 134 charging pile officially put into use in Shenzhen. Of which 10.515 million yuan investment in the completion of a major operations center is currently charging station known as “the largest footprint and invest in the charging station”, the toshiba laptop battery station covers an area of 1092 square meters, can accommodate 12 cars into electric.

Including FAW, Dongfeng Group, Chery, Geely and even the hippocampus cars, public vehicles, including Thailand, the domestic sales of the top 30 most of the auto companies have had electric car development plans, and developed several production models can be .  

According to Ge Jia car prices published at different times of the electric car production and development program, the domestic electric cars to participate in the project by up to 50 more than the car companies. If the qualification does not get the car production of agricultural and other types of enterprises taken into account, the enterprise engaged in production of electric cars as many as 100 or more.  

However, the implementation of each company’s batteries, motors and charging equipment, technical standards and specifications not consistent. This became the biggest difference between each company, but also its efforts to fight for the right of standard-setting lies. toshiba pa3178u-1brs battery,toshiba pa3191u-1brs battery,toshiba pa3191u-2brs battery.
