Battery breakthrough set to accelerate electric-car development

A team of scientists working at the Massachusetts Institute of Technology are claiming a significant breakthrough in recharging times for lithium-ion batteries. According to findings published in the scientific journal Nature, MIT researchers Byoungwoo Kang and Gerbrand Ceder have unlocked the potential of lithium-ion batteries by patenting a unique process which is claimed to allow a typical laptop power pack to be fully recharged in less than a minute--an improvement in recharging performance of roughly 90 percent over existing lithium-ion batteries. Lithium-ion batteries generate electric current via the flow of lithium ions across an electrolyte, from an electrode to a cathode.
