AI Technical Summary

Technical Problem

In existing technologies, lithium cobalt oxide is prone to agglomerated particles and twins during sintering, which leads to a decline in material performance.

Method used

Before sintering lithium cobalt oxide, pretreatment methods such as pressing, leveling, and cutting are used to make the reaction of each part of the sintering material more balanced, ensure sufficient air intake and exhaust channels, and reduce the generation of agglomerated particles and twins.

🎯Benefits of technology

This effectively reduced the agglomerated particles and twins in lithium cobalt oxide materials, synthesized larger lithium cobalt oxide particles with more complete single crystallization, and improved the sintering effect.

Abstract

The application provides a pretreatment method for optimizing sintering effect of lithium cobalt oxide and application thereof. The pretreatment method comprises the following steps: placing lithium cobalt oxide sintering mixture to be sintered into a sintering container, pressing and flattening, obtaining a total block to be sintered, and then cutting, entering the next sintering process. Before sintering of the lithium cobalt oxide, the method of pressing and flattening the sintering mixture and then cutting is adopted, so that the reaction of each part of the sintering material is more balanced, the generation of agglomerated particles and twin crystals of the lithium cobalt oxide is reduced, and thus the single-crystal synthesis of the large-particle lithium cobalt oxide is more sufficient.
