Description
Summary:Solid‐state batteries (SSBs) have garnered significant attention in the critical field of sustainable energy storage due to their potential benefits in safety, energy density, and cycle life. The large‐scale, cost‐effective production of SSBs necessitates the development of high‐performance solid‐state electrolytes. However, the manufacturing of SSBs relies heavily on the advancement of suitable solid‐state electrolytes. Composite polymer electrolytes (CPEs), which combine the advantages of ordered microporous materials (OMMs) and polymer electrolytes, meet the requirements for high ionic conductivity/transference number, stability with respect to electrodes, compatibility with established manufacturing processes, and cost‐effectiveness, making them particularly well‐suited for mass production of SSBs. This review delineates how structural ordering dictates the fundamental physicochemical properties of OMMs, including ion transport, thermal transfer, and mechanical stability. The applications of prominent OMMs are critically examined, such as metal–organic frameworks, covalent organic frameworks, and zeolites, in CPEs, highlighting how structural ordering facilitates the fulfillment of property requirements. Finally, an outlook on the field is provided, exploring how the properties of CPEs can be enhanced through the dimensional design of OMMs, and the importance of uncovering the underlying “feature‐function” mechanisms of various CPE types is underscored. The manufacturing of solid‐state batteries depends on the development of suitable solid‐state electrolytes. One potential solution is to develop composite polymer electrolytes (CPEs) that combine the strengths of inorganic fillers and polymer electrolytes. The recent advances made in the development of CPE chemistry and technology enabled by ordered microporous materials, including metal–organic frameworks, covalent organic frameworks, and zeolites, are summarized.
