Ferrotitanium slag-based sagger for sintering positive electrode material of lithium ion battery, and preparation method of sagger
The invention relates to a ferrotitanium slag-based sagger for sintering a positive electrode material of a lithium ion battery, and a preparation method of the sagger. According to a technical scheme in the invention, the method comprises the following steps: carrying out ball milling on the ferrotitanium slag until a particle size is less than or equal to 100 microns, carrying out mechanical pressing, carrying out heat treatment at 1430-1450 DEG C, and performing crushing and screening to obtain a material A with a particle size of 0.2-1 mm, a material B with a particle size of 60-80 microns and a material C with a particle size of less than or equal to 40 microns; stirring the material B, the material C, rho-alumina micro powder and dextrin to obtain mixed fine powder; and stirring the material A and the mixed fine powder, adding water, carrying out stirring, ageing, forming and drying successively, and carrying out heat treatment at 1400-1420 DEG C for 4-5 hours to prepare the ferrotitanium slag-based sagger for sintering of the positive electrode material of the lithium ion battery. The method has the advantages of high resource cyclic utilization rate, simple process and low production cost, and the produced sagger has excellent sintering performance, strong erosion resistance and good thermal shock resistance.
本发明涉及一种基于钛铁渣的锂离子电池正极材料烧结用匣钵及其制备方法。其技术方案是：将钛铁渣球磨至粒度≤100μm，机压成型，在1430～1450℃热处理，破碎，筛分，得到粒度为0.2～1mm的物料A、粒度为60～80μm的物料B和粒度≤40μm的物料C；将物料B、物料C、ρ‑氧化铝微粉和糊精搅拌，得混合细粉料；将物料A与混合细粉料搅拌，加水搅拌，困料，成型，干燥，在1400～1420℃条件下热处理4～5小时，制得基于钛铁渣的锂离子电池正极材料烧结用匣钵。本发明资源化循环利用率高、工艺简单和生产成本低，其制品烧结性能优良、抗侵蚀性能强和热震稳定性好。
