Abstract: 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.
