Application of continuous feeding and discharging rotary tube furnace in the battery materials industry

The continuous feeding and discharging rotary tube furnace is widely used in the battery materials industry, mainly reflected in the following aspects:

1. Preparation of positive and negative electrode materials for batteries
Sintering and calcination: The continuous feeding and discharging rotary tube furnace can be used for the sintering and calcination process of positive and negative electrode materials for lithium-ion batteries. By precisely controlling the atmosphere and temperature inside the furnace, the electrochemical performance of the material can be improved, and the energy density and cycle life of the battery can be increased.
Efficient production: The design of continuous feeding and discharging makes the production process of battery materials more efficient, reducing waiting time and downtime, and improving production efficiency.

2. Material performance optimization
Uniform heating: The rotating design of the rotary tube furnace ensures that the material is uniformly heated inside the furnace, avoiding local overheating or undercooling and helping to optimize the performance of battery materials.
Atmosphere control: By precisely controlling the atmosphere inside the furnace, such as introducing inert or reducing gases, the performance of battery materials can be further improved, such as increasing their conductivity and reducing internal resistance.

3. New material research and development
Experimental platform: The continuous feeding and discharging rotary tube furnace provides an ideal experimental platform for the research and development of new materials for battery materials. Researchers can synthesize and test the properties of new materials under different atmospheres and temperature conditions, exploring their potential applications in the field of batteries.
Flexible adjustment: Parameters such as furnace atmosphere, temperature, and material movement speed can be adjusted according to specific experimental needs, providing more possibilities for the development of new materials.

4. Actual case
Sintering of lithium battery materials: There is equipment that can achieve sintering of 1200 degree lithium battery materials. The furnace body can be designed to tilt for easy feeding and discharging, and is equipped with automatic feeders and receiving tanks for continuous feeding and discharging. This device has played an important role in the preparation of lithium battery materials.
Preparation of solar cell materials: Rotary tube furnaces are also used for the preparation of solar cell materials, such as the preparation of negative electrode materials for silicon-based solar cells. By using ultrafast Joule heating technology to control the thermal interaction between carbon and silicon phases, a “rivet point” of silicon carbide is formed, effectively solving the phase separation problem in traditional heat treatment processes.
