Hierarchical micro/nano porous silicon Li-ion battery anodes

A wet-chemical etching method is reported for the scale-up preparation of carbon-coated hierarchical micro/nano porous silicon powders as a Li-ion battery anode, which shows no capacity fading at 1500 mA h g(-1) in 50 charge/discharge cycles.
