Preparation method of high-performance zinc-polyaniline secondary battery

Abstract

The invention discloses a preparation method of a high-performance zinc-polyaniline secondary battery. The preparation method comprises the following steps: preparation of a positive plate: adopting home-made graphite paper as a positive current collector, and preparing polyaniline on the graphite paper; preparation of a negative plate: adopting a home-made zinc / carbon composite material as a negative active material, mixing the zinc / carbon composite material with a conductive agent, a binder and a solvent to form a sizing agent, coating the sizing agent on the current collector, drying, roll forming and cutting into slices to prepare the cathode plate; assembling: putting the positive plate, a membrane and the negative plate into a battery shell in a laminated manner, after a pole lug is welded with a pole column, sealing the battery and injecting an electrolyte, and adding glass fiber paper for capping. The zinc-polyaniline secondary battery prepared in the invention is high in safety performance, low in preparation cost, high in utilization rate of positive and negative active substances and excellent in cycle performance.
