摘　　要：Metal-organic frameworks(MOFs),with their ultrahigh specific surface area,uniformly distributed pores,and tunable structures,are promising candidates for next-generation active electrode materials in lithium-ion batteries(LIBs).However,their application is hindered by poor cycling stability due to structural collapse during charge-discharge cycles.To address this issue,we developed an alloy and multi-solvent thermal method strategy to synthesize Co/Zn bimetallic MOFs based on Naphthalenetetracarboxylic acid(NTCA).The resulting petal-like Co/Zn-NTCA MOF demonstrates outstanding electrochemical performance.The incorporation of zinc ions not only significantly enhances cycling stability but also markedly increases the specific capacity of the anode material.At a current density of 200 mA·g^(-1),the Co/Zn(2:1)-NTCA MOF demonstrated an impressive reversible capacity of 956 mA·h·g^(-1) after 150 cycles.Even after 500 cycles,the specific capacity of the electrode remained high,with a value of 438 mA·h·g^(-1) at a current density of 1000 A·g^(-1).
