Magnesium cobaltate positive target material of thin-film magnesium battery, preparation method and thin-film magnesium battery
The invention relates to a magnesium cobaltate positive target material of a thin-film magnesium battery, a preparation method and the thin-film magnesium battery, and belongs to the technical field of magnesium batteries. The preparation method comprises the following steps: mixing magnesium salt powder with cobaltosic oxide powder to obtain mixed powder; putting the mixed powder into a ball-milling tank to be mixed with zirconium oxide balls, then adding a dispersing agent, continuously mixing, and carrying out ball-milling; then adding a binder into the ball milling tank, and continuing ball milling; sieving the ball-milled synthetic powder with a 500-mesh sieve, weighing the sieved synthetic powder, pouring the sieved synthetic powder into a vibration mold, and pressurizing to form a mold-pressed blank; putting the blank into a cold isostatic press, pressurizing and maintaining the pressure to obtain a magnesium cobaltate anode target blank subjected to cold isostatic pressing; and putting the magnesium cobaltate anode target blank into an atmosphere sintering furnace or a vacuum sintering furnace, carrying out multi-section heat preservation and multi-section cooling, and naturally cooling to room temperature along with the furnace to obtain the magnesium cobaltate anode target of the thin-film magnesium battery. The magnesium cobaltate anode target material of the thin-film magnesium battery prepared by the invention is uniform in component and convenient for thin-film deposition.
本发明涉及一种薄膜镁电池钴酸镁正极靶材、制备方法及薄膜镁电池，属于镁电池技术领域。制备方法包括：将镁盐粉末与四氧化三钴粉末混合得到混合粉末；将混合粉末放入球磨罐内与氧化锆球相混合，然后添加分散剂继续混合、球磨；然后在球磨罐内添加粘结剂，继续球磨；球磨后的合成粉过500目的筛，过筛的合成粉经称重后，倒入震动模具内，加压，形成模压的坯料；将坯料放入冷等静压机内加压并保压，得到冷等静压后的钴酸镁正极靶材坯料；将钴酸镁正极靶材坯料放入气氛烧结炉内或者放入真空烧结炉内，进行多段保温、多段降温后，随炉自然冷却到室温，得到薄膜镁电池钴酸镁正极靶材。本发明制得的薄膜镁电池钴酸镁正极靶材的成分均匀，便于薄膜沉积。
