Abstract
The commercial development of lithium ion batteries (LIBs) have been hampered from the uncontrollable growth of Li dendrites and low coulombic efficiency (CE). In this respect, the exploration of advanced host materials to regulate the behavior of Li plating/stripping is an effective strategy to resolve those issues. In this work, we report the modified Ni foam by Au nanoparticles decorated reduced graphene oxide (rGO) as effective Li host (denoted as Au@rGONi). Thus-prepared Li host enabled a stable CE as high as 96.5% after 100 cycles at a current density of 1 mA cm −2 with a capacity of 1 mAh cm −2 . The according symmetric cell delivered a long-term lifespan of 1000 h without obvious voltage fluctuation under 0.5 mA cm −2 /1 mAh cm −2 . More encouragingly, a full LIB based on the Au@rGONi-300 anode and LiFeO 4 cathode demonstrated excellent discharge-charge cycling behavior with a high capacity of 130.5 mAh g −1 after 140 cycles at 0.2C. This work presents the feasibility to develop stable lithium metal anodes by surface modification of commercial Ni foam with lithiophilic materials. • Commercial 3D Ni foam has been modified to be effective Li metal host. • Au particles decorated rGO is introduced to realize uniform Li plating/stripping. • High Coulombic efficiency and long-term lifespan are delivered. • Uniform and smooth surface of Li without dendrites after 100 cycles is obtained. • Potential practical viability of as-prepared Li host is demonstrated.
