Firing sagger of lithium cobalt oxide positive electrode material and preparation process
The invention relates to the technical field of saggers for roasting lithium battery positive electrode materials, in particular to a sintering sagger for a lithium cobalt oxide positive electrode material and a preparation process. A composite layer is arranged at the inner bottom of the sagger; the sagger comprises the following raw materials in percentage by weight: 18-20% of cordierite, 30-32% of mullite, 20-21% of spinel, 19-20% of aluminum oxide and 9-10% of kaolin. The composite layer comprises the following raw materials in percentage by weight: 88-90% of spinel, 7-9% of zirconium dioxide and 2-3% of corundum powder. The composite layer has the characteristic of extremely high alkali material corrosion resistance, and the sagger body has excellent rapid cooling and rapid heating resistance, so that the sagger has alkali resistance, rapid cooling and rapid heating resistance and sustainability, the performance of a battery can be improved, the service life of the battery can be prolonged, and the reliability of the battery can be improved.
本发明涉及锂电池正极材料焙烧用匣钵技术领域，具体为一种钴酸锂正极材料的烧制匣钵及制备工艺，匣钵的内底部设置有复合层；匣钵包括以下重量百分比的原料：堇青石18～20％、莫来石30～32％、尖晶石20～21％、氧化铝19～20％、高岭土9～10％；复合层包括以下重量百分比的原料：尖晶石88～90％、二氧化锆7～9％、刚玉粉2～3％。本发明中复合层具有极强的抗碱材料腐蚀的特点，而匣钵钵体具有优良的耐急冷急热的性能，使得匣钵具有抗碱性、耐急冷急热性能和可持续性，进而能提升电池性能，增加其寿命和可靠性。
