A preparing method of a ternary-material lithium battery saggar

Abstract

The invention relates to a preparing method of a ternary-material lithium battery saggar. Synthetic mullite is adopted as a main raw material, and the mass of the synthetic mullite accounts for 70% of the total mass. Synthetic cordierite is adopted as a main auxiliary material, a wax mixing agent is added, and the mass of the synthetic cordierite and the wax mixing agent accounts for 30% of the total mass. The ternary-material lithium battery saggar is prepared by subjecting the main raw material and the main auxiliary material to granule smashing and graduation in order by a sand powder preparing device, mixing and fully stirring by a mixing and pulping device into which the wax mixing agent is added in advance so as to complete preparation of pulp used for a product blank, further stirring by a molding device, vacuumizing, removing bubbles, cooling, molding, discharging components of the wax mixing agent in the product blank by a wax discharging device, firing the product blank by a firing device, subjecting the product blank to external and internal surface treatment by a surface treatment device, and drying. The technical scheme of the method can effectively reduce the saggar cost, improve product quality and prolong service lifetime of the product.

Description

technical field [0001] The invention relates to refractory material technology, and mainly proposes a preparation method of a ternary material lithium battery containing burning sagger. Background technique [0002] With the acceleration of the global industrialization process, oil and coal will be gradually exhausted in the next few years. As the global energy will become more and more scarce, the development of new energy is the only way for countries to solve the energy crisis. [0003] Therefore, countries now regard the development and utilization of lithium batteries as a new energy source that can replace oil and coal in the future, and formulate main contents and long-term plans as soon as possible. [0004] As a representative of new energy, the lithium battery industry has become one of the fastest growing industries in the world. The rapid development of lithium batteries has led to a surge in demand for lithium battery cathode materials, and the battery material...

Problems solved by technology

[0010] To sum up, the ceramic saggers used for firing lithium battery materials currently use the above two preparation processes. The ternary series materials are the most advanced lithium battery materials at present, and the requirements for the saggers are very high. The ternary materials are generally in the The positive electrode material is produced by melting and crystallizing at a high temperature of 1100°C. Its use conditions are harsh and its technical performance is high. It is a key consumable part in the production process of lithium battery materials. The quality of the current domestic ceramic saggers is far behind that of Japan and other countries. Products The number of times of use is low and the cost is high. A considerable part of the saggers required by battery material manufacturers rely on imports. The annual import of such saggers costs tens of millions of yuan.
