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 lithium ion batteries, in particular to a double-layer structure sagger for a lithium battery positive electrode material and a preparation method of the double-layer structure sagger. The sagger with the double-layer structure comprises an outer layer and an inner layer, the thickness of the outer layer is 10-15 mm, the thickness of the inner layer is 2-3 mm, the outer layer is made of raw materials with large particle sizes, the outer layer is made of raw materials with small particle sizes, and the raw materials of the outer layer are cordierite, mullite, alumina, kaolin and borate glass; the inner layer is made of nano zirconia, cordierite, mullite, alumina spinel, aluminum oxide, kaolin and borate glass, the porosity of the sagger is greatly reduced and the strength of the sagger is improved by accurately controlling the particle size distribution of raw material particles and vacuumizing and pressurizing the interior of a forming mold in a forming process, so that the service life of the sagger is greatly prolonged.
本申请涉及锂离子电池技术领域，尤其涉及一种锂电池正极材料用双层结构匣钵及其制备方法。双层结构匣钵包括外层和内层，外层的厚度为10～15mm，内层的厚度为2‑3mm，外层采用颗粒粒径较大的原料，外层采用颗粒粒径细小的原料：外层原料为堇青石、莫来石、美铝尖晶石、氧化铝、高岭土和硼酸盐玻璃；内层原料为纳米氧化锆、堇青石、莫来石、美铝尖晶石、氧化铝、高岭土和硼酸盐玻璃，通过对原料颗粒粒径分布的精准控制和成型工艺中对成型模具内部进行抽真空并加压，大幅度降低了匣钵气孔率，提升其强度，进而大幅度提升匣钵使用寿命。
