Double-layer composite structure sagger for lithium battery positive electrode materials and preparation method of sagger
The invention relates to the technical field of sagger kiln furniture preparation, and provides a double-layer composite structure sagger for lithium battery positive electrode materials and a preparation method of the sagger. The double-layer composite structure sagger for the lithium battery positive electrode materials comprises an inner layer and an outer layer. The preparation method of the double-layer composite structure sagger for the lithium battery positive electrode materials comprises the steps of preparation of an outer-layer structure green body, preparation of an inner-layer structure green body, processing forming, drying, high-temperature sintering and the like. The double-layer composite structure sagger for the lithium battery positive electrode materials prepared by the method has the advantages of good corrosion resistance, high cycle use frequency, long service life, small thermal expansion coefficient, excellent thermal shock resistance and certain bearing strength, the positive electrode materials are easy to peel off when being in contact with the sagger, the sagger is free of peeling and slag falling in the use process, is free of pollution, is suitable for the sintering process of various lithium battery positive electrode materials, and is beneficial to reducing the production cost and improving the economic benefit.
本发明涉及匣钵窑具制备技术领域，提出一种锂电池正极材料用双层复合结构匣钵及其制备方法。上述锂电池正极材料用双层复合结构匣钵包括内层和外层。锂电池正极材料用双层复合结构匣钵的制备方法包括制备外层结构生坯、制备内层结构生坯、加工成型、干燥和高温烧结等步骤。采用该方法制得的锂电池正极材料用双层复合结构匣钵，具有良好的耐腐蚀性能，循环使用次数多，寿命长，有较小的热膨胀系数，优良的热震稳定性和一定的承压强度，而且正极材料与该匣钵接触时易剥落，使用过程中匣钵不起皮，不掉渣，无污染，适用于多种锂电池正极材料烧结过程，有利于降低生产成本，提高经济效益。
