Building better solid-state batteries with silicon-based anodes

When the mass ratio of Si and HC is larger than 6:4, Li dendrites still occurred. For the anodes with too much HC (Si:HC = 2:8), the reversible capacity is severely scarified; thus, the mass ratio of Si and HC was optimized as 4:6 (noted as LiSH46). In this case, although the sintering process of Si still occurred, a dense, uniform, and coherent anode is also generated
