1、Overview and principle of lithium battery Muffle furnace
Lithium battery Muffle furnace, also known as closed furnace heat treatment equipment, is one of the widely used equipment in the battery manufacturing process. It consists of heating furnace body, temperature control system, atmosphere gas control system and so on. The Muffle furnace provides heat energy through resistive heating elements, and the temperature control system ensures accurate control of the temperature in the furnace. At the same time, the atmosphere composition in the furnace can be adjusted through the atmosphere gas control system to meet different heat treatment needs.

(3) Optimize the crystallization and growth process of the material
The Muffle furnace can provide a high-temperature heat treatment environment to promote the crystallization and growth of the crystal of the battery material. By precisely controlling temperature and time parameters, the crystal structure of the material can be optimized, the conductivity and ion migration rate of the material can be improved, and the power density and cycle performance of the battery can be improved.
(4) Reduce the occurrence of oxidation reaction
Muffle furnace in the heat treatment process can create a low oxygen environment, reduce the occurrence of oxidation reaction. For some battery materials, such as the lithium negative electrode in lithium metal batteries, the low-oxygen environment can effectively inhibit the oxidation reaction and reduce the self-discharge and safety risks of the battery.
3、the operation process of lithium battery Muffle furnace
(1) Preparation
Before heat treatment of battery materials, the Muffle furnace needs to be cleaned and inspected to ensure that the equipment is in good condition.

(3) Load materials
Put the battery material to be treated into the Muffle furnace, and ensure the appropriate loading density to avoid excessive accumulation affecting the heat transfer.
(4) Run the heat treatment program
Start the furnace body heating system, raise the temperature of the Muffle furnace to the set value, and keep it for a certain time, so that the material can get proper heat treatment.
(5) Cool and remove the material
After the end of the heat treatment process, gradually reduce the temperature of the Muffle furnace, and after the temperature drops to the safe range, the treated battery material can be removed.
