摘要
Abstract To meet the growing demand for safe and high‐energy batteries, particularly for the commercialization of electric vehicles, a need for further advancement has arisen. An innovative and promising solution for current collectors in LIBs is a metallized plastic current collector (MPCC) with metal‐polymer‐metal multilayer composite structure. This approach offers several advantages. First, it effectively reduces the inert weight and thickness of LIBs, thereby enhancing their energy density. Second, a polymer with electrical insulation and high elongation properties in the MPCC significantly improves the safety performance of LIBs by preventing thermal runaway. Despite its potential for large‐scale application in LIBs, the MPCC still faces significant challenges, such as weak interfacial adhesion force and low electrical conductivity. Therefore, researchers in the field of energy storage are currently focusing on the design, modification, and development of practical MPCCs. Hence, in this review various polymers, preparation approaches, and MPCCs are comprehensively analyzed and summarized. Additionally, detailed discussions are provided on the advances, key issues, improvements and corresponding mechanisms associated with MPCCs. Finally, valuable guidance and future directions are provided for the design and improvement of advanced MPCCs in high‐energy LIBs, thus facilitating the commercialization process.
