Composite structure sagger for lithium battery positive electrode material and preparation method of composite structure sagger
The invention discloses a composite structure sagger for a lithium battery positive electrode material and a preparation method of the composite structure sagger, and relates to the technical field of sagger kiln furniture preparation. When the composite structure sagger for the lithium battery positive electrode material is prepared, mullite, cordierite and corundum are soaked in a furfuryl alcohol aqueous solution, oxalic acid is added for polymerization, and then high-temperature calcination is performed to prepare carbon-coated mullite, carbon-coated cordierite and carbon-coated corundum; mullite, cordierite, corundum, leucite, yellow dextrin and water are mixed to serve as a sagger outer layer, carbon-coated mullite, carbon-coated cordierite, carbon-coated corundum, leucite, yellow dextrin and water are mixed to serve as a sagger inner layer, the inner layer structure and the outer layer structure are subjected to composite compression molding and then calcined, and the composite structure sagger for the lithium battery positive electrode material is prepared. The prepared composite structure sagger for the lithium battery positive electrode material has the advantages of being high in breaking strength, good in thermal shock resistance and good in erosion resistance.
本发明公开了一种锂电池正极材料用复合结构匣钵及其制备方法，涉及匣钵窑具制备技术领域。本发明在制备锂电池正极材料用复合结构匣钵时，先将莫来石、堇青石、刚玉分别在糠醇水溶液中浸渍，加入草酸聚合后高温煅烧制得碳包覆莫来石、碳包覆堇青石、碳包覆刚玉；将莫来石、堇青石、刚玉、白榴石、黄糊精、水混合作为匣钵外层，将碳包覆莫来石、碳包覆堇青石、碳包覆刚玉、白榴石、黄糊精、水混合作为匣钵内层，内外层结构复合压制成型后煅烧制得锂电池正极材料用复合结构匣钵。本发明制备的锂电池正极材料用复合结构匣钵具有抗折强度高、抗热震性能好、抗侵蚀性能好的优点。
