Battery Breakthroughs: Progress for Electric Cars

A breakthrough that could propel electric cars to the mass market—that's the buzz about a recent study out of Massachusetts Institute of Technology. Here's the gist of the research, published in the journal Nature: Scientists Byoungwoo Kang and Gerbrand Ceder tweaked the surface structure of lithium ion phosphate, a material commonly used to make batteries. The tweak allows the material to conduct electricity very quickly and handle repeated charges without degrading, making it possible to have smaller, lighter, quick-charging batteries.
