Sagger for positive electrode material of lithium battery and preparation method of sagger
The invention relates to the technical field of lithium ion batteries, in particular to a sagger for a lithium battery positive electrode material and a preparation method of the sagger. Comprising the following raw materials in parts by mass: 10-30 parts of cordierite, 10-20 parts of mullite, 10-40 parts of magnesium aluminate spinel, 10-40 parts of aluminum oxide, 20-30 parts of kaolin and 10-50 parts of borate glass, through precise control of particle size distribution and vacuumizing and pressurization of the interior of a forming mold in a forming process, the porosity of the sagger is reduced, the strength of the sagger is improved, and the strength of the sagger is improved. And 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匣钵及其制备方法。包括以下质量份数的原料：堇青石10‑30份，莫来石10‑20份，美铝尖晶石10‑40份，氧化铝10‑40份，高岭土20‑30份，硼酸盐玻璃10‑50份，通过对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，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。
