Lithium battery graphitization furnace

Graphitization Furnaces can significantly improve the performance of negative electrode materials, making them more suitable for applications such as lithium-ion batteries. In the application field of negative electrode material graphitization furnace, the lithium battery industry is undoubtedly its main service target.
With the advent of larger screens and diversified functions in digital terminal products, new requirements have been put forward for battery life. Natural graphite and artificial graphite are currently the main anode materials for lithium-ion batteries. In order to change their turbostratic structure and increase the specific capacity of the battery, high-temperature processing of the anode materials is currently an effective way for some relevant manufacturers. This equipment is used for high-temperature graphitization of lithium battery anode materials.

Product Characteristics

- the negative electrode graphite material has a large heat capacity, its stacking specific gravity is small, in the high-temperature treatment is completed is not very suitable for the use of gas circulation method of fast cooling structure, a disc using natural cooling, in order to improve the production effect, the conventional practice, that is, a power supply to control the 3-4 high-temperature furnace body, at any time there is only one warming up, and the other is in the cooling down state. Conventional type has 1 drag 2, 1 drag four, 1 drag 6.
-?touch screen or industrial control machine automatic control record process parameters, PLC programmable and touch screen display system, intelligent temperature control table and PLC to achieve data communication.
-?the use of closed internal circulation of pure water cooling system; digital flow monitoring system, each way water by the flow meter monitoring and protection.
-?in order to adapt to the specific gravity of carbon/graphite powder lighter characteristics of this equipment, vacuum piping, switch, air intake, exhaust are set to PID control slow open and slow close device.
-?The exhaust pipe is designed to be thickened and shortened, which can effectively prevent the dust from accumulating and blocking the exhaust port.
-?According to the requirement of vacuum degree, Roots pump can be added, and the vacuum degree can reach 100Pa.
-?Different anode materials will produce volume expansion and impurity volatilisation phenomenon at different temperature points, which will cause sudden change of pressure in the furnace, so this setup is specially designed to increase the inlet and outlet gas automatic balancing system. (Vacuum pressure controller through the PID controller through the inlet and outlet gas solenoid valve closed loop to achieve).
-?the use of high-performance gas purifier, the oxygen content of the gas can be reduced to 1PPM, dew point temperature can be reduced to -65 ℃.
-?Multi-functional operation desk can achieve remote control, up to 150 metres away.
