Lithium metal anode is a promising candidate anode in lithium‐sulfurized polyacrylonitrile (SPAN) batteries. Nevertheless, the formation of lithium dendrites is recognized as the worst problem for lithium metal batteries. Herein, a hybrid solid interphase is synthesized on lithium with a facile method. This modified lithium anode can not only suppress lithium dendrites, but also gives rise to a fast interfacial transport mechanism. When used in a lithium‐SPAN battery, a reversible capacity of 450 mAh g −1 (based on SPAN) is delivered at 10 A g −1 , which is a promising candidate for high specific power batteries.
