Thin film magnesium battery magnesium cobalt oxide positive electrode target material, preparation method and thin film magnesium battery

Abstract

The present application relates to a kind of thin film magnesium battery magnesium cobaltate positive target material, preparation method and thin film magnesium battery, belong to magnesium battery technical field.Preparation method includes: magnesium salt powder is mixed with tricobalt tetroxide powder to obtain mixed powder;Mixed powder is placed in ball mill jar and mixed with zirconium oxide ball, then dispersing agent is added and continue to mix and ball mill;Then add binder in ball mill jar, continue to ball mill;Synthetic powder after ball milling is passed through 500 mesh screen, after weighing, pour into vibration mold, pressurize, form die pressed blank;Blank is placed in cold isostatic press and pressurized and pressure holding, obtain magnesium cobaltate positive target material blank after cold isostatic pressing;Magnesium cobaltate positive target material blank is placed in atmosphere sintering furnace or placed in vacuum sintering furnace, after multi-section heat preservation, multi-section cooling, with furnace natural cooling to room temperature, obtain thin film magnesium battery magnesium cobaltate positive target material.The composition of the thin film magnesium battery magnesium cobaltate positive target material prepared by the present application is uniform, which is convenient for thin film deposition.
