New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

A team at Stanford University has developed stable silicon Li-ion battery anodes by incorporating a conducting polymer hydrogel into the Si-based material. A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si.
