thium batteries could charge in 10 seconds

Engineer of the United States in new ways to create more compact, more durable, faster charging lithium batteries, the charging time may be required only a few seconds. It's getting difficult to overstate the importance of battery technology. Compact, high-capacity batteries are an essential part of portable electronics already, but improved batteries are likely to play a key role in the auto industry, and may eventually appear throughout the electric grid, smoothing over interruptions in renewable power sources. Unfortunately, battery technology often involves a series of tradeoffs among factors like capacity, charging time, and usable cycles. Today's issue of Nature reports on a new version of lithium battery technology that may just be a game-changer. Massachusetts Institute of Technology in the United States a group of engineers at journals "Nature" published a research report that this technology allows mobile phones and computer charging time is much shorter, but also can be used to create a better battery for electric vehicle use . Because of the new batteries are widely used in the application of the old material, so trust can be listed in a few years. The advantages of lithium batteries are very able to store energy, charge and discharge disadvantage are very slow. The scientific community has always believed that the lithium battery charge and discharge is due to slow charge is responsible for carrying the lithium-ion (lithium ion) moving too slow. However, this group of engineers to rely on computer models five years ago after the operator found that common lithium iron phosphate battery materials (lithium iron phosphate) in the lithium-ion velocity is very quick. Cede Group members said they found that slow down the lithium-ion batteries are moving speed of the material structure. So they changed the production of materials and structure, so that lithium ion can move quickly. Research group take advantage of this a new kind of materials, create a charging time required is only 10-20 seconds of lithium batteries.
