Issues Concerning Interfaces with Inorganic Solid Electrolytes in All-Solid-State Lithium Metal Batteries

All-solid-state batteries have attracted wide attention for high-performance and safe batteries. The combination of solid electrolytes lithium metal anodes makes high-energy practical next-generation devices. However, when a electrolyte replaces the liquid electrolyte, many different interface/interphase issues arisen from contact with electrodes. Poor wettability unstable chemical/electrochemical reaction at interfaces will lead to poor diffusion kinetics combustion fresh active materials in electrolyte. Element cross-diffusion charge layer formation cathodes also impede ionic conductivity increase transfer resistance. abovementioned interface hinder electrochemical performance all-solid-state This review demonstrates mechanism these between anodes/cathodes. Aiming address problems, we propose modification strategies weaken resistance improve
