Team doubles battery life
A team of South Korean researchers has found a way to make lithium batteries 90 percent more efficient than current batteries. A Tuesday report says an applied chemistry professor at Hanyang University, Cho Jae-phil, leads the team of researchers, and claims that the new technology will allow the batteries in notebook PCs and cellphones to last eight times longer than conventional batteries. The significant capacity boost was made possible thanks to using three-dimensional porous silicon particles made of silica and hydrogen fluoride instead of graphite in the negative electrode.
