Lithium ion batteries may benefit from porous amorphous silicon anodes

Next-generation anodes for lithium ion batteries will probably no longer be made of graphite. Silicon, which is a related material, can provide a much higher capacity than graphite, but its crystallinity poses problems. In the journal Angewandte Chemie, Chinese scientists have introduced a porous silicon form that is amorphous, not crystalline, and has the potential to outstrip the other materials in rechargeable battery applications.
