Summary:

The present invention provides a MOF-based single-atom lithium-supplemented composite material and preparation method thereof, a cathode material and a battery. The MOF-based single-atom lithium supplementation composites contain lithium salts and carbonized derivatives prepared by calcination and acid etching after impregnating with MOF transition metal salt solution, which can be used in lithium-ion battery systems to reduce the decomposition potential of lithium supplementation additives and reduce the first-cycle Coulombic efficiency.
