ALD Derived Li2O Layer Stabilizing Solid Electrolyte Interphase of Silicon/Carbon Anodes for Lithium Storage

Carbon Energy, EarlyView.
A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.
