Annealing method of magnesium cobaltate positive target material of thin-film magnesium battery, positive target material and battery
The invention relates to an annealing method of a magnesium cobaltate positive target material of a thin-film magnesium battery, the positive target material and the battery, and belongs to the technical field of magnesium batteries. The annealing method comprises the following steps: after adopting three-section heat preservation, cooling to 175-185 DEG C along with a furnace, continuously preserving heat, and then naturally cooling to room temperature along with the furnace to obtain the annealed magnesium cobaltate anode target material of the thin-film magnesium battery. The heat preservation temperature of the second section is larger than the heat preservation temperature of the first section and smaller than the heat preservation temperature of the third section, and the heat preservation temperature of the third section is 445-455 DEG C. The magnesium cobaltate anode target material of the thin-film magnesium battery, which is obtained by the annealing method, has the advantages of uniform components, no segregation, good grain size consistency, no cracks, no layering and no bumps in the target material, convenience in processing during subsequent machining, and convenience in thin-film deposition during preparation of the all-solid-state thin-film magnesium battery.
本发明涉及一种薄膜镁电池钴酸镁正极靶材的退火方法、正极靶材及电池，属于镁电池技术领域。退火方法采用三段保温后，随炉冷却至175～185℃继续保温，然后随炉自然冷却到室温，得到退火后的薄膜镁电池钴酸镁正极靶材；第一段保温温度＜第二段保温温度＜第三段保温温度，第三段保温温度为445～455℃。本发明的退火方法处理得到的薄膜镁电池钴酸镁正极靶材的成分均匀，无偏析，晶粒大小一致性好，靶材内无裂纹，无分层，无鼓包，在后续机加工时方便加工，并且也便于全固态薄膜镁电池制备时的薄膜沉积。
