Optimizing Current Collector Interfaces for Efficient “Anode‐Free” Lithium Metal Batteries

Advanced Functional Materials, Год журнала: 2023, Номер 34(6)

Опубликована: Окт. 27, 2023

Abstract Current lithium (Li)‐metal anodes are not sustainable for the mass production of future energy storage devices because they inherently unsafe, expensive, and environmentally unfriendly. The anode‐free concept, in which a current collector (CC) is directly used as host to plate Li‐metal, by using only Li content coming from positive electrode, could unlock development highly energy‐dense low‐cost rechargeable batteries. Unfortunately, dead Li‐metal forms during cycling, leading progressive fast capacity loss. Therefore, optimization CC/electrolyte interface modifications CC designs key producing efficient batteries with liquid solid‐state electrolytes. Lithiophilicity electronic conductivity must be tuned optimize plating process Li‐metal. This review summarizes recent progress findings design (e.g. 3D structures) its interaction
