Interface science in polymer‐based composite solid electrolytes in lithium metal batteries

Solid-state lithium metal batteries (SSLMBs) have attracted considerable attention as one of the most promising energy storage systems owing to their high safety and density. Solid electrolytes, particularly polymer-based composite solid electrolytes (CSEs), are considered electrolyte candidates for SSLMBs. However, wide application is inhibited by various electrochemical issues, such low ionic conductivity, growth dendrites, poor cycling stability, which related interface issues within In this review, parameters interfaces in CSE SSLMBs, including between polymer matrix inorganic fillers, CSEs cathode, anode, examined. Relevant corresponding remediation strategies proposed. Finally, future perspectives based on interfacial engineering characterization polymer/inorganic filler interactions proposed building high-performance use
