摘要
Abstract
Construction of three-dimensional framework with high lithiophilicity and conductivity can inhibit the lithium dendrites growth and mitigate the volume change,thus improving the cycling stability and electrochemical performance of lithium metal anodes(LMAs).Ni3Se4 nanoscale modified three-dimensional frameworks(Ni3Se4@NF)was obtained by selenizing nickel foam using chemical vapor phase reaction.A series of physicochemical characterization and electrochemical performance tests were carried out.The results indicate that uniformly distributed Ni3Se4 nanoscales provide plenty of active sites for Li-ion nucleation,effectively reduces the nucleation barrier and induce a uni-form lithium deposition.In addition,the in-situ formed Li2Se-rich solid electrolyte interface(SEI)has excellent ionic conductivity and mechanical strength,which promotes rapid Li-ion transport and en-hances interfacial stability.Benefit from this,the Coulombic efficiency and life-span of LMAs are sig-nificantly improved.关键词
