Abstract
The invention relates to a method and application of a multifunctional interface layer modified composite zinc cathode based on zinc blende in zinc metal batteries. Zinc blende powder is produced by crushing and ball milling, then mixed with a solvent and wet screened. The fine zinc blende is dried and mixed with a surfactant to obtain grafted fine powder. This modified powder is combined with a binder and organic solvent to form a slurry, which is coated on the zinc metal cathode. After drying, the modified composite zinc metal cathode is applied to aqueous zinc metal batteries. This method stabilizes the zinc cathode, isolates electrolyte corrosion, inhibits zinc dendrite growth, and addresses issues of dendrite formation, hydrogen evolution, and corrosion, thereby extending the battery's service life.
