Double-layer structure sagger for lithium battery positive electrode material and preparation method of double-layer structure sagger
The invention relates to the technical field of sagger kiln furniture preparation, and provides a double-layer structure sagger for a lithium battery positive electrode material and a preparation method of the double-layer structure sagger. The double-layer structure sagger for the lithium battery positive electrode material comprises a base body layer and a surface coating. The preparation method of the double-layer structure sagger for the lithium battery positive electrode material comprises the steps of premixing aggregate, processing and forming, mixing and pulping a surface coating, drying, sintering at high temperature and the like. The sagger with the double-layer structure for the positive electrode material of the lithium battery, which is prepared by adopting the method, has good corrosion resistance of resisting erosion of Li<+>, Co<2+> and the like, is high in cycle use frequency, long in service life, relatively small in thermal expansion coefficient, excellent in thermal shock resistance and certain in bearing strength, the positive electrode material is easy to peel off when being in contact with the sagger, the sagger is not peeled off in the use process, no slag falling and no pollution is generated, the product is an ideal improved product of the current cordierite-mullite sagger, is suitable for the sintering process of various lithium battery cathode 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结构匣钵及其制备方法。上述锂电池正极材料用双层结构匣钵包括基体层和表面涂层。锂电池正极材料用双层结构匣钵的制备方法包括预混骨料、加工成型、表面涂层混合制浆，以及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结构匣钵，具有良好的抗Li+、Co2+等侵蚀的耐腐蚀性能，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，是当前堇青石‑莫来石类匣钵的理想改进品，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。
