| Sumario: | Metallic Lithium have gained great attention for its high theoretical specific capacity. But continuous growth of Li dendrites upon cycling might cause low coulombic efficiency and serious security issues. Construction of advanced 3D Cu current collectors to regulate Li plating/stripping and improve battery performance is considered as one effective promising strategy. In this chapter, we will discuss the roles and requirements of current collectors in lithium metal batteries. Then methods (dealloying, powder-sintering and 3D printing) employed for construction of 3D Cu current collector and implementation of surface modification (lithiophilic sites and coating layers) will be illustrated. At last, future opportunities of Cu current collectors will be lifted out. |
