The invention relates to the technical field of sagger kiln preparation, in particular to a preparation method of a sagger for firing a lithium battery cathode material. The preparation method comprises the following steps of S1, raw material mixing; S2, forming; S3, drying; S4, preheating; and S5, sintering. The sagger prepared according to the preparation method has high corrosion resistance, long service life, smaller thermal expansion coefficient, excellent thermal shock stability and certain strength, the cathode material is easy to peel off when in contact with the sagger, the sagger isslag-free and pollution-free and is not peeled in the using process; the sagger has the innate advantages of energy saving and consumption reduction, and is an ideal substitute for the mullite saggerat present; and the preparation method is suitable for the sintering process of multiple lithium battery cathode materials such as lithium cobalt oxides, ternary materials, lithium manganate and lithium iron phosphate and is resistant to high temperatures of 1,200 DEG C or above, and the service life of the sagger is 20 times that of domestic saggers, and is 3 to 4 times that of similar foreign saggers.
本发明涉及匣钵窑具制备技术领域，特别涉及一种烧成锂电池正极材料用匣钵的制备方法，包括以下步骤：S1.原料混合；S2.成型；S3.干燥；S4.预热；S5.烧结。采用该方法制得的匣钵具有良好的耐腐蚀性能，使用寿命超长，较小的热膨胀系数，优异的热震稳定性和一定的强度，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；具有节能降耗的先天优势，是目前莫来石匣钵的理想替代品；适用于钴酸锂、三元材料、锰酸锂、磷酸铁锂等多种锂电池正极材料烧结过程耐1200℃以上高温，使用寿命是国内匣钵的20倍，国外同类匣钵的3‑4倍。
