Technical paste: phone / notebook battery Why would explode?

Compared with other secondary battery technology, lithium-ion battery is lighter, cheaper, and higher energy density. It has become now the main form of rechargeable batteries, from cell phones, laptops to cars and various items of business jets in the use of lithium-ion batteries. This battery has a small problem - they are not only short-circuit, also caught fire and exploded. Consider the following Gizmodo website introduction:

The lithium-ion battery is the reason why there will be an explosion tendency, is called a "thermal runaway" process (thermal runaway) to blame. In essence, "thermal runaway" is an energy positive feedback loop process: the elevated temperature will result in the system heats, the system heats at elevated temperatures, which in turn, make the system more heat. Thermal runaway is a very common phenomenon, from the concrete curing (heat) will release a large number of physical and chemical processes of stellar explosion (supernova is a product of cosmic thermal runaway), are likely to appear thermal runaway.

The lithium-ion battery thermal runaway. Such as both ends of a 9V battery is a coin bridging the tear film-like isolation of the anode and cathode of the lithium-ion battery will cause a short circuit, short circuit often will cause thermal breakdown. The cause of the fire of the lithium-ion batteries also include: ambient temperature exceeds 60 ° C, often overcharge unauthorized modification shell.

Whatever the reason, cobalt oxide experienced this reaction are battery chemicals. Valence Technology R & D vice president Joe La Mule (Joe Lamoreux) explained: "If you heat the chemicals reach a certain temperature, it begins to self-heating, and then developed into a fire and explosion." In some case, such an organic electrolyte releasing the pressure will cause the cell to rupture. If exposed to high temperature environment, or is experiencing a spark, it may also will burn.

Although this uncontrollable reaction does not happen often, but the base number of the lithium-ion battery is too large, we feel that such incidents often occur. For example, in 2006, almost all the major laptop manufacturers - Apple, Hewlett-Packard, Toshiba, Lenovo, Dell and other companies - have received a report of a small amount of battery overheating condition recall products. Single apple a 9 report in the recall of 1.8 million units PowerBook and iBook. More importantly, the number of the battery size, configuration and the battery cell (cell) will affect the intensity of thermal runaway. Small battery pack (such as digital SLR cameras) are only a few battery power, thermal runaway propagation from the battery unit to the other unit is relatively low. And 787 huge battery pack is another matter: they are packed in sealed metal box, which can not be discharged waste heat, the result is that when a battery unit hot enough to ignite the electrolyte, and the rest of the battery unit will quickly with into.

But you also do not need to worry too much. Your notebook is not a ticking time bomb. To do some maintenance on a regular basis, the lithium-ion battery will be safe and reliable work. Lithium-ion life is not long, generally two to three years can be maintained (whether you use it). Because of this, all of the lithium-ion battery pack should be about every 36 months on the replacement. Moreover, whenever the charge is reduced to 50% of the time, you should can it enrich my knowledge. No memory effect of lithium-ion, but the voltage is too low will make them serious damage.

Tablet PC shipments ultra-PC is not far off: the fourth quarter or inflection point

IDC data show that global tablet PC shipments reached 52.5 million in the fourth quarter of 2012, PC shipments of approximately 89.8 million units. Although a difference of more than 3700 million units, but take into account the high-speed growth of the tablet market will continue, while the PC market is likely to continue to decline, the industry inflection point may not be far off.

Sina Technology Luo Liang

A year ago, the Goldman Sachs Technology and Internet Conference, Apple CEO Tim Cook (Tim Cook) said that this tablet computer like the iPad could one day more than the PC market. Now look, this time point may have gradually clear.

The market research firm IDC, released on February 19, "Worldwide Quarterly PC Tracker report," the fourth quarter of 2012, global PC shipments of 89.8 million units, a year-on-year decline of 6.4%. This is the global PC sales fell for the first time in five years.

Correspondingly, the Tablet PC market is continuing to show explosive growth. IDC previously published data show that the fourth quarter of 2012, total global tablet PC shipments hit a record high, reaching 52.5 million units, a year-on-year growth of 75.3%.

"Although the growth rate will slow down, but in the fourth quarter of 2013, global tablet PC shipments are likely to be more than the PC." ISuppli company's consumer electronics and semiconductors, principal analyst Gu Wenjun said.

PC camp fight back

Once the tablet computer shipments more than a PC, Apple founder Steve Jobs's "post-PC era" argument may become undisputed. But before this, the PC camp, led by Microsoft, Intel will not easily admit it.

As the world's second-largest PC maker, Lenovo Group has been claiming that now is PC + era PC based on user demand products morphological changes will still be in the dominant position. Lenovo Group CEO Yang Yuanqing has pointed out that the meeting in March last year, shipments of notebook computers are still more than three years after the Tablet PC.

Yang said at the time, "The PC is not static, and the future will be a new architecture next laptop will absorb the advantages of tablet PCs, will be lighter, thinner, battery life will be longer, of course, also can touch. better than the tablet PC laptop, it can create content, not just the consumer, read the content.

In fact, in the past few months, the Lenovo Yoga, represented by the integration of the products of tablet PCs and PC experience has become the PC makers race to launch the product, the these deformation PC products caused some impact on the Tablet PC.

Apple CEO Cook has stressed on more than one occasion, Tablet PC shipments exceeded PC is just a matter of time, but industry analysts believe, Tablet PC shipments are unlikely to exceed a PC. IDC research vice director Wang Jiping on Sina science and technology, the Tablet PC is less than a volume of more than PC trend.

"Heavy users as well as commercial users will choose the PC, although mild Tablet PC users will choose, but as the smart phone screen more and more, many consumers will give up the Tablet PC and turn smart phones. Deformation PC products will also impact the Tablet PC. "said Wang Jiping.

Relative to the view of Wang Jiping, mobile industry analyst Samir Singh (Sameer Singh) forecasts extraordinarily radical. Singh said yesterday that the trend of tablet PC market with intelligent machines market trends are very similar, in contrast, the Tablet PC to replace the PC faster. He expects global sales of tablet PCs in the first quarter of this year is expected to surpass PC sales.

Surface Pro this to where? Solve battery life and other issues is fundamental

February 17, Microsoft recently formally consumer-oriented launched Surface Pro Tablet PC, compared with October last year, the Surface RT, Surface Pro built-in the full version of Windows 8 operating system, equipped with a performance more outstanding Intel i5 processor, you can run all current desktop applications and games, can be said that the Windows RT operating system, and can only run Windows Store Application Surface RT upgraded version. However, with the configuration and system upgrades, Surface Pro in weight and thickness corresponding increase and Surface Pro Surface RT even from the looks of it only from the external keyboard and stand up to distinguish. Windows 8 devices can be compatible with a common application tablet PCs and traditional notebook combo actually facing what the fate of it?
Microsoft launched Windows 8 operating system, aimed at the desktop, laptop and tablet PC models system the unified support touch interface and a traditional desktop applications can be run across two areas of the tablet and the computer, the two clever combination. Surface RT position became Microsoft has excellent battery life, and to meet consumers into the entertainment needs of the office most of the Tablet PC; Surface Pro is more like a "beast", "we can see it as it is a computer with a strong performance of high-end laptop. "Microsoft Surface of conference to describe Surface Pro. Surface Pro as a Tablet PC and notebook is both products is, indeed, pay some small price.
Line to the performance of the traditional notebook Microsoft Surface Pro obviously made a compromise, the biggest regret is that the battery life of the Surface Pro and use angle Surface Pro problems. How bad battery life I believe that everyone has some understanding from the evaluation and the actual use of the online users Surface Pro as a notebook, either on his knees or an ordinary desk, Surface Pro use some unstable and not comfortable to use, such a thing would never happen in the body of the traditional notebook products.
Some people view the Surface Pro MacBook and iPad comparison, although of Surface Pro and Apple products are some similarities, but after all Surface Pro neither MacBook, nor is the iPad. Gartner technology analyst Michael Gartenberg Surface Pro up in some ways can be said that the mixture of the Tablet PC and laptop. Surface Pro perfect creative interpretation of the combination of the Tablet PC and notebook, to allow consumers to only use a single device to be able to experience the use of two different feel. However, for other traditional notebook manufacturers are not in the form of this combo showed a lot of enthusiasm, we currently do not determine the route to go in Surface Pro is the correct choice.
Microsoft's intention is to want a device to replace the combination of notebook and tablet PCs, but most people really do not quite willing to spend $ 1,000 (about 6200 yuan) to buy a Tablet PC, although Surface Pro can run common desktop applications, but must pass through from the point of view of the pure, Surface Pro with traditional notebook there are still a considerable gap. IPad has just come out when there is a considerable part of the iPad is not optimistic that the iPad is just a huge iPod touch ", but later facts show that the the iPad success or confirms the huge market potential of the Tablet PC. With the iPad, Surface Pro can now be called is a new device, and is no longer just an ordinary tablet PC. The current view of Microsoft's "Combo" strategy or market demand, but the view from its infancy, considerable Surface Pro impact in the industry, but the situation is not optimistic sales. For iPad consumers and not the so-called "iPad RT" and "iPad Pro" choice for Microsoft Surface Pro is the most urgent problem is, we must allow consumers to ascertain Surface RT The Surface Pro what difference.
Although other OEM manufacturers also try similar production and Surface Pro equipment, but also did not a can perfect alternative to traditional notebook and Tablet PC products was born. Products on the market are usually just ordinary touch Tablet PC external keyboard and make them look like a laptop. But Microsoft has recently started to show, Surface Pro is just a start, Microsoft has begun to develop the next generation of Surface Pro. Microsoft Surface departments responsible for Panos Panay recently said in an interview with ABC television, the next generation of Surface Pro has improved adjustable bracket and battery problems, is an exciting choice. Microsoft in China to establish a production line, also said Microsoft will increase its production scale, fully prepared for the next generation of Surface products.
