| Abstract | Lithium dendrites caused by nonuniform Li+ flux leads to the capacity fade and short-circuit hazard of lithium metal batteries. The solid electrolyte interface (SEI) is critical to the uniformity of Li+ flux. Here, an ultrafast preparation of uniform and vertical Cu7S4 nano-flake arrays (Cu7S4 NFAs) on the Cu substrate is reported. These arrays can largely improve the lithiophilicity of the anode and form Li2S-enriched SEI due to the electrochemical reduction of Cu7S4 NFAs with lithium. A further statistical analysis suggests that the SEI, with a higher content of Li2S, is more effective to inhibit the formation of lithium dendrites and yields less dead lithium. A quite stable coulombic efficiency of 98.6% can be maintained for 400 cycles at 1 mA cm(-2). Furthermore, at negative to positive electrode capacity ratio of 1.5 (N/P = 1.5), the full battery of Li@Cu7S4 NFAs||S shows 83% capacity retention after 100 cycles at 1 C, much higher than that of Li@Cu||S (33%). The findings demonstrate that high Li2S content in the SEI is crucial for the dendrite inhibition to achieve better electrochemical performance. |
