Abstract:

With the rapid development of electric vehicles and portable electronic products, high-energy- density rechargeable batteries have been strongly considered. Owing to its ultra-high theoretical capacity and low reduction potential, lithium(Li) metal is strongly regarded as one of the promising anodes for the next- generation secondary batteries. However, the formation of Li dendrites and volume expansion of Li limit the practical applications of Li metal anode. Introducing three-dimensional(3D) host in Li anode can regulate behavior of Li plating/stripping and alleviate volume expansion. The lithiophilic host can reduce the nucleation overpotential of Li, induce uniform Li nucleation, and effectively regulate the Li deposition behavior. In this review, the research progress of lithiophilic host in Li metal anode is summarized. The lithiophilic host is classified according to the different lithiophilic materials. The effect of lithiophilic host on inhibiting the growth of lithium dendrites and improving the performance of batteries is summarized, and the future research and deve-lopment are prospected.

Key words: High-energy-density battery, Li metal anode, Li dendrite, Lithiophilic host
