Understanding silicon failure opens up research path for higher-capacity lithium-ion batteries (IMAGE)
Caption
Photos of silicon nanowires grown on a stainless steel disk shown (clockwise from top left) in side, top, and macroscopic views. The disk is about the size of a quarter. New research in Nature Nanotech has discovered the processes that have limited use of silicon in lithium-ion batteries and has identified a research path to overcome them. Batteries with silicon anodes have 10 times the electrical storage capacity of batteries with typical graphite-based anodes.
