摘  要:Interface is a necessary channel of carrier permeation in sulfide-based all-solid-state lithium battery(ASSLB).Homogeneous and fast lithium-ion(Li^(+))interfacial transport of cathode is the overriding premise for high capability of ASSLBs.However,the inherent transport heterogeneity of crystalline materials in cathode and the cathode active material(CAM)/sulfide solid electrolyte(SSE)interfacial issues result in high interfacial imped-ance,decreasing the Li^(+)transfer kinetics.In this review,we outline the Li^(+)transport properties of CAMs and SSEs,followed by a discussion of their interfacial electro-chemo-mechanical issues.Commentary is also provided on the solutions to the multiple-scale interfacial Li^(+)transport failure.Furthermore,the underlying interdependent mechanisms between electrodes are summarized and overviewed.Finally,we suggest future paths to better comprehend and promote the interfacial Li^(+)transport in ASSLBs.This review provides an in-depth understanding of cathodal interfacial issues and the proposed improvement strategies will provide guidance for further advancement of high-performance ASSLBs.
