Abstract
AbstractLithium (Li) metal batteries have attracted great attention as next‐generation high‐energy‐density storage systems due to the high theoretical energy density and low redox potential of Li metal. However, the safety concerns and poor cycle life are hindering the commercialization of Li metal batteries. Combination of Li metal and current collectors to regulate Li plating/stripping behaviors is an effective strategy to address these issues. In this review, the recent advances in the current collectors for composite Li metal anodes are summarized, including construction interfacial protective layers on current collectors, fabrication and utilization of 3D current collectors, and improving the surface lithiophilicity for current collectors. Finally, perspectives of the current limitations and the future research directions are also presented.
