Lithium battery material repair core equipment
At present, the solid phase sintering method is relatively widely used in the repair of lithium iron phosphate positive electrode materials. After the missing iron, phosphorus and lithium elements of the lithium iron phosphate powder are supplemented in proportion, high temperature calcination is carried out in an inert atmosphere or a reducing atmosphere to repair the crystal structure and restore the electrochemical activity.

The KeZhong Intelligent Team has many years of experience in designing and manufacturing core equipment for coating and granulation of lithium battery materials. The newly developed sealed energy-saving pyrolysis system also originated from the coating unit that controls the oxygen content more accurately. In the solid-phase sintering repair process, KeZhong provides crushing method powder removal and high-temperature impurity removal solutions and core equipment customization services.
Features:
In the crushing method, the aluminum content of the powder can be controlled at 0.3%
The equipment port has a small sealing area, and is equipped with three layers of sealing: mechanical, graphite ring, and nitrogen to achieve more precise anaerobic control; high filling rate structural design and low nitrogen consumption; a spring-loaded explosion relief valve is configured to deal with extreme situations, making pyrolysis safer.
The vacuum pressure vessel is designed and manufactured at the same level, and the internal materials are corrosion-resistant and durable. Multi-sensor detection is connected to the control system to achieve monitorable, sustainable and stable production.
