摘      要：Owing to the unique structure,anode-free lithium metal batteries(AFLMBs)have higher energy density and lower production cost than traditional lithium metal batteries(LMBs)or lithium-ion batteries(LIBs),However,AFLMBs suffer from an inherently finite Li reservoir and exhibit poor cycle stability,low Coulombic efficiency(CE)and severe dendrite *** this work,polydiallyl lithium disulfide(PDS-Li)was successfully synthesized and coated on Cu current collector by electrochemical *** PDS-Li acts as an additional lithium resource to compensate for the irreversible loss of lithium during *** addition,the special structure and lithiophilicity of PDS-Li contribute to lower nucleation overpotential and uniform lithium *** coupled with Li-rich manganese-based(LRM)cathode of Li1.2Mn0.54Ni0.13Co0.13O2,the anode-free full cell exhibits significantly improved cycle stability over 100 cycles and capacity retention of 63.3%and 57%after 80 and 100 cycles,*** believe that PDS-Li can be used to ensure stable cycling performance and high-energy-density in AFLMBs.
