NOVELTY - Method for preparing a cathode material of a zinc ion battery, involves using a plasma treatment to prepare the cathode materials of the zinc ion batteries. USE - Method for preparing cathode material of zinc ion battery used in large scale energy storage, wearable electronic energy storage devices, aqueous zinc ion battery, a zinc solid-state battery, a zinc vanadium battery, a zinc manganese battery secondary battery (all claimed). ADVANTAGE - The cathode material has excellent conductivity, uniform electric field distribution and good control ability of zinc ion, can reduce the polarization of the electrode and effectively inhibit generation and growth of zinc dendritic crystal. The reversible service life of the zinc ion battery cathode materials is improved effectively.
