Replacing organic liquid electrolytes (LEs) in lithium‐ion batteries (LIBs) with solid‐state electrolytes (SSEs) to achieve all‐solid‐state lithium batteries (ASSLBs) with improved safety and potential higher energy density has been attracting growing attention for their wide application in various electronic devices, electric vehicles and renewable energy integration. To achieve high‐performance ASSLBs, the design of SSEs with high ionic conductivity, easy processability, and compatible and stable interfaces with the cathode and anode has become a research priority in recent years. Among all the challenges and issues concerning interfaces, the mechanisms and suppression methods of interfacial reactions are particularly important in the rational design of efficient electrolyte/electrode interfaces. This review mainly focuses on interfacial reactions in various types of inorganic ASSLBs and significant negative effects on battery performance. We also highlight advanced characterization methods and summarize some notable approaches to stabilize interfaces. Finally, we believe the scientific prospect of ASSLBs interface research will be helpful to keep pace with future research trends.

“…Moreover, the strong inter-and intra-molecular force of the fluorine groups induces an improvement in the mechanical properties of polymer matrix. As a result, PVDF is usually employed as polymer matrix in blended SPE [44] and composite polymer electrolyte (CPE) [45,46] to benefit from those advantages. Furthermore, when the current density is increasing, an in situ interface layer generates between lithium anode and PVDFbased SPE to avoid the risk of over-current.…”

In the development of solid‐state lithium batteries, solid polymer electrolyte (SPE) has drawn extensive concerns for its thermal and chemical stability, low density, and good processability. Especially SPE efficiently suppresses the formation of lithium dendrite and promotes battery safety. However, most of SPE is derived from the matrix with simple functional group, which suffers from low ionic conductivity, reduced mechanical properties after conductivity modification, bad electrochemical stability, and low lithium‐ion transference number. Appling macromolecular design with multiple functional groups to polymer matrix is accepted as a strategy to solve the problems of SPE fundamentally. In this review, macromolecular design based on lithium conducting groups is summarized including copolymerization, network construction, and grafting. Meanwhile, the construction of single‐ion conductor polymer is also focused herein. Moreover, synergistic effects between the designed matrix, lithium salt, and fillers are reviewed with the objective to further improve the performance of SPE. At last, future studies on macromolecular design are proposed in the development of SPE for solid‐state batteries with high energy density and durability.
