The method comprises the steps of dissolving a divalent copper metal compound and a non-ionic polymer to obtain a first solution, dissolving trimesic acid to obtain a second solution, and mixing the first and second solutions to obtain a copper-based metal-organic framework. The dried precursor are mixed with ionic liquid, which has contained a first lithium salt, and then dried to obtain an anion impregnated copper-based metal-organic framework. Thereafter, an anion impregnated copper-based metal-organic framework, a second lithium salt, polymer materials, and a second solvent are mixed to obtain the anode passivation slurry. The anode passivation slurry homogenizes the concentration of conduction of lithium ions and improves ionic conductivity, reducing the formation of lithium dendrites, and improving the cycle life of batteries.
