Thin film magnesium battery zirconium magnesium phosphate solid electrolyte target, method of manufacture and battery

Abstract

The present application relates to thin film magnesium battery zirconium magnesium phosphate solid electrolyte target material, preparation method and thin film magnesium battery, belong to magnesium battery technical field. Including: magnesium salt powder is mixed with diaphosphorus pentoxide and zirconium oxide powder to obtain mixed powder; the mixed powder is put into a closed ball mill tank and mixed with zirconium oxide balls, then a dispersing agent is added and mixed and ball milled; then a binder is added to the ball mill tank and ball milled; the synthesized powder after ball milling is sieved through a 500 mesh sieve, the sieved synthesized powder is poured into a vibrating mold, pressed, and a die pressed blank is formed; the blank is put into a cold isostatic pressing machine and pressed and pressure maintained, to obtain a zirconium magnesium phosphate solid electrolyte target material blank after cold isostatic pressing; the zirconium magnesium phosphate solid electrolyte target material blank is put into an atmosphere sintering furnace or a vacuum sintering furnace, after multi-stage heat preservation, the furnace is naturally cooled to room temperature, to obtain a thin film magnesium battery zirconium magnesium phosphate solid electrolyte target material. The composition of the solid electrolyte target material of the present application is uniform, facilitating thin film deposition.
