Prelithiation of silicon/graphite composite anodes

Prelithiation of silicon/graphite-based composite anodes is a promising strategy to limit Li-ion battery capacity loss over long cycling We report on the spontaneous-corrosion-driven-lithiation (SCDL) of lithium metal on the anode surface of a-Si/c-FeSi 2 /graphite//LiNi 0 6 Mn 0 2 Co 0 2 O 2 cells and compare it to electrochemically-driven-lithiation (EDL)
