The invention belongs to the technical field of lithium battery positive electrode materials, and discloses a silicon carbide sagger for a lithium battery positive electrode material and a preparationmethod thereof. The preparation method comprises a sagger substrate and a working layer pressed on the inner surface of the sagger substrate. The sagger substrate is prepared from the following raw materials in parts by weight: 60-75 parts of silicon carbide powder, 15-25 parts of clay, 5-10 parts of nanometer zirconium oxide, 5-10 parts of aluminum oxide powder, 5-10 parts of a binding agent and10-20 parts of water. The working layer is prepared from the following raw materials in parts by weight: 30-40 parts of silicon carbide powder, 20-30 parts of aluminum oxide powder, 10-20 parts of organic silicon resin, 1-10 parts of talcum powder, 1-3 parts of graphene and 2-8 parts of water. The prepared silicon carbide sagger is high in corrosion resistance, the bonding performance of an anti-corrosion layer and a sagger body is good, service life is prolonged, and recycling of the sagger body can be achieved.
本发明属于锂电池正极材料技术领域，公开一种用于锂电池正极材料的碳化硅匣钵及其制备方法，包括匣钵基体和压制在匣钵基体内表面的工作层；所述匣钵基体由如下重量份的原料制备所得：碳化硅粉体60‑75份，粘土15‑25份，纳米氧化锆5‑10份，氧化铝粉5‑10份，结合剂5‑10份，水10‑20份；所述工作层由如下重量份的原料制备所得：碳化硅粉体30‑40份，氧化铝粉20‑30份，有机硅树脂10‑20份，滑石粉1‑10份，石墨烯1‑3份，水2‑8份。本发明制备的碳化硅匣钵抗腐蚀能力强，防腐层与钵体的结合性好，延长了使用寿命，能实现钵体的回收利用。
