 A new solution has been developed to prevent the formation of dendritic growth in aqueous zinc metal batteries. Polyacrylonitrile coatings were applied to the zinc anodes, which improved the hydrophilicity of the zinc anode and regulated ion transport, thereby reducing the risk of dendrite formation. This method was found to be effective in prolonging the cycle life of the batteries, as well as increasing the efficiency of the batteries.
