To address the corrosion and dendrite issues of lithium metal anodes,a protective layer was ex-situ con-structed by P4S10 modification.It was determined by X-ray photoelectron spectroscopy and Raman spec-tra that the main constituents of the protective layer were P4S10,Li3PS4 and other LixPySz type deriva-tives.The protective layer was proved to be effective to stabilize the interphase of lithium metal.With the modified Li anodes,symmetric cells could deliver stable Li plating/stripping for 16000 h;Li-S batter-ies exhibited a specific capacity of 520 mA h g-1 after 200 cycles at 1000 mA g-1 with average Coulombic efficiency of 97.9％.Therefore,introducing LixPySz based layer to protect Li anode provides a new strategy for the improvement of Li metal batteries.
