摘要：

Lithium metal batteries are promising candidates for next generation high energy batteries. However, an undesirable dendrite growth hinders their practical applications. Herein, a three-dimensional (3D) porous carbon nanotube film decorated with Ag nanoparticles (CNT/Ag) has been synthesizedviathe thermal decomposition reaction of AgNO(3)into Ag nanoparticles, and then is transformed into a 3D porous CNT/Ag/Li filmviathermal infusion to obtain a high-performance free-standing lithium host. This as-formed 3D CNT/Ag/Li host can effectively restrain the dendrite growth by guiding Li depositionviathe highly lithiophilic Ag nanoparticle seeds and lowering local current density of the highly conductive matrix. The as-prepared CNT/Ag/Li electrode exhibits long-term cycling stability over 200 cycles at a current density of 1 mA cm(-2)with an areal capacity of 1.0 mA h cm(-2). Moreover, the full cell paired with a sulfur/C cathode shows good cycling stability. Therefore, the 3D porous CNT/Ag/Li film formedviaa facile three-step fabrication process can enlarge the cycle lifetime of a lithium metal anode.
