MIT jemmy limits Lithium-ion
The engineers at MIT (Massachusetts Institute of Technology) have discovered a breakthrough that allows the battery based on Lithium-ion (Li-ion, which is found in laptop and mobile phone) is made smaller, lighter and re-filled (recharge) with far more quickly. MIT days so the announcement Wednesday.
Gerbrand Ceder, Professor Materials Science & Engineering at MIT, assisted by Byoungwoo Kang, a student program of study has created a small battery that can be filled or emptied in full within 10 to 20 seconds.
Detailed explanation on how they can do this has been published in the Nature magazine March 12 edition , but here there will be a short Recap on what they have to do.
Li-ion batteries do have a meeting of energy (energy density) is high, but they are also popular and can not be filled quickly emptied. That is why the need for hours to fill the re-power the battery on the vehicle.
Electric vehicle pioneer still wrestle with this problem battery. Have some ideas to overcome this problem. Better Place, for example, have an idea where the rider electric vehicle can save time by switching the battery with the battery fully empty dots in the car electrical services.
Ceder Kang and experiment with how ion Lithium-ion entry and moving around the lithium iron phosphate, a material often used in Li-ion battery. They developed a new surface structure so that the ion-ion can migrate quickly, mengumpamakan results of their work such as making a toll road memutari a city to avoid traffic jams, with some of the tunnel so that someone can leave the toll direct path to the destination.
"The ability and fill empty the battery in seconds rather than minutes allows applications and new technologies change the lifestyle," according to the paper's Ceder and Kang in Nature.
In addition to much faster, the battery with the new material is also lost much less storage capacity than Li-ion battery normal after repeatedly emptied (discharge) and re-filled during the test. Therefore, they believe that their batteries can be manufactured with less material, so it is lighter and smaller.
Because the invention of Ceder and Kang is not the material that is entirely new, but only changes in the structure of the material, the two researchers stated that the material they can be implemented as a commercial battery within 2 or 3 years. (CNET)
Comment by pepoluan ™: This article is its focus on batteries for electric vehicles. However, not closed the possibility that results of research and Ceder Kang applied to other devices, such as a laptop or mobile phone. Imagine, a laptop that takes only 10-20 seconds for a refill. Or mobile phone that takes only 5 seconds before the full-charge! With the speed of such, it is possible to create phones that feature more sophisticated, with a battery that is quite resistant 1 day only. Yet if the refill is not how long.
