High-Performance Macroporous Bulk Silicon Anodes Synthesized by Template-Free Chemical Etching

Three‐dimensional porous silicon particles can be produced via the combination of a galvanic displacement reaction and a metal‐assisted chemical etching process. This simple synthetic route can be applied to make high‐performance anode materials, including high specific capacity, stable cycling rete...

Description
Summary:Three‐dimensional porous silicon particles can be produced via the combination of a galvanic displacement reaction and a metal‐assisted chemical etching process. This simple synthetic route can be applied to make high‐performance anode materials, including high specific capacity, stable cycling retention, and high rate capability, in lithium‐ion batteries.
