Abstract
Dendrites growth and unstable interfacial Li+ transport hinder the practical application of lithium metal batteries (LMBs). Herein, we report an active layer of 2,4,6-trihydroxy benzene sulfonyl fluorine on copper substrate that induces oriented Li+ deposition and generates highly crystalline solid-electrolyte interphase (SEI) to achieve high-performance LMBs. The lithiophilic -SO2- groups of highly crystalline SEI accept the rapidly transported Li+ ions and form a dense inner layer of LiF and Li3N, which regulate Li+ plating morphology along the (110) crystal surface toward dendrite-free Li anode. Thus, Li||Cu cells with lithiophilic SEI achieve an average deposition efficiency of 99.8% after 700 cycles, and Li||Li cells operate well for 1100 h. Besides, Li||LiNi0.8Co0.1Mn0.1O2 cells with modified SEI exhibit a capacity retention that is 14 times than that of conventional SEI. Even at -60 oC, Li||Cu cells reach stable deposition efficiency of 83.2% after 100 cycles.
