Lithium battery negative electrode graphitization furnace

After the large screen and diversified functions of digital terminal products, new requirements have been put forward for the battery life. Natural graphite and artificial graphite as the main anode material of lithium-ion battery at present, in order to change the structure of its chaotic layer and improve the specific capacity of the battery, high temperature graphitising the anode material is an effective way for some relevant manufacturers at present. This equipment is used for high temperature graphitising treatment of anode materials for lithium battery.

High Temperature Graphitization Furnace Product Parameter

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 light specific gravity of carbon powder/graphite powder, the vacuum pipes, switches, air intake, and exhaust of this high-temperature graphitization furnace are all set as PID-controlled slow-opening and slow-closing devices.
- The exhaust pipe is designed to be thickened and shortened, which can effectively prevent the dust from accumulating and blocking the exhaust port.
- The lithium battery negative electrode graphitization furnace can be equipped with a Roots pump according to the vacuum degree requirements, 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.
