Ceramic sagger for whisker-reinforced calcined lithium battery positive electrode material and preparation method of ceramic sagger
The invention relates to a ceramic sagger for a whisker-reinforced calcined lithium battery positive electrode material and a preparation method of the ceramic sagger. According to the technical scheme, the preparation method comprises the following steps: dry-mixing sepiolite mineral fine powder, aluminum oxide fine powder, fused magnesite fine powder and metal micro powder and ceramic membrane microcapsules, watering, wet-mixing, granulating and screening; mixing the sieved particles with three granularities with one kind of fine powder, and carrying out mechanical pressing, drying and sintering to obtain a ceramic reinforced block material; crushing and screening to obtain three kinds of ceramic reinforced aggregate particles and one kind of ceramic reinforced matrix fine powder; then premixing the ceramic reinforced matrix fine powder and the metal micro powder at the ceramic membrane microcapsules, stirring the premixed ceramic reinforced matrix fine powder and the metal micro powder at the ceramic membrane microcapsules with the three ceramic reinforced aggregate particles, watering, stirring, mechanically pressing, drying, firing, and naturally cooling to prepare the ceramic sagger for the whisker reinforced calcined lithium battery positive electrode material. The method is low in production cost, simple in process and high in yield; the prepared product is high in strength, good in thermal shock resistance, excellent in erosion resistance and long in service life.
本发明涉及一种晶须增强煅烧锂电池正极材料用陶瓷匣钵及其制备方法。其技术方案是：将海泡石矿物细粉、氧化铝细粉、电熔镁砂细粉和金属微粉@陶瓷膜微胶囊干混，洒水，湿混，造粒，筛分；将筛分后的三种粒度的颗粒和一种细粉混合，机压成型，干燥，烧成，得到陶瓷增强块体料；经破碎和筛分，得到三种陶瓷增强骨料颗粒和一种陶瓷增强基质细粉；然后将陶瓷增强基质细粉和金属微粉@陶瓷膜微胶囊预混，预混后与三种陶瓷增强骨料颗粒搅拌，洒水，搅拌，机压成型，干燥，烧成，自然冷却，制得晶须增强煅烧锂电池正极材料用陶瓷匣钵。本发明生产成本低、工艺简单和成品率高；所制制品强度高、抗热震性能好、抗侵蚀性能优异和使用寿命长。
