Application of Experimental Multi zone Rotary Furnace in the New Energy Industry

The application of experimental multi zone rotary furnaces in the new energy industry is extensive and in-depth, mainly reflected in the following aspects:

1. Preparation and Performance Optimization of Battery Materials
Lithium ion battery materials: Multi temperature zone rotary furnaces can be used for the preparation and performance testing of positive electrode materials (such as ternary materials, lithium iron phosphate) and negative electrode materials (such as graphite, silicon-based materials). By simulating the temperature changes of batteries in actual working environments, the multi temperature zone rotary furnace can accurately control the temperature distribution inside the furnace tube, meet the processing requirements of battery materials under different temperature conditions, and thus prepare battery materials with better performance and stronger stability. For example, in an oxygen atmosphere, the use of a multi zone rotary furnace can achieve ordered growth of layered structures of ternary materials, with an initial charge discharge efficiency increased to 92%.
Sodium ion battery materials: Similar to lithium-ion batteries, multi temperature zone rotary furnaces can also be used for the preparation and performance testing of sodium ion battery materials, promoting the development and application of sodium ion battery technology.
Fuel cell materials: In the field of fuel cells, multi temperature zone rotary furnaces can be used to prepare key materials such as catalysts and electrolytes, and their performance can be evaluated through performance testing. By precise temperature control and atmosphere management, the required fuel cell materials can be synthesized.

2. Preparation of solar cell materials
The multi temperature zone rotary furnace can provide a high-temperature, high vacuum or atmosphere protection environment for the preparation of solar cell materials, meeting special process requirements. For example, in the preparation of negative electrode materials for silicon-based solar cells, ultrafast Joule heating technology is used to control the thermal interaction between carbon and silicon phases, forming silicon carbide “rivet points”, effectively solving the phase separation problem in traditional heat treatment processes, and ensuring a strong bond between graphene and silicon.

3. Preparation of energy storage materials
In the preparation of energy storage materials, multi temperature zone rotary furnaces also play an important role. For example, in the preparation of positive and negative electrode materials for lithium batteries, high-temperature thermal shock strategy can be used to quickly synthesize positive electrode materials. This strategy not only has low energy consumption and time consumption, but also can synthesize materials with excellent battery performance.

4. Lithium ion battery recycling and processing
The multi temperature zone rotary furnace can be used for the heat treatment process of waste lithium-ion batteries, effectively recovering valuable metals from waste batteries through heat treatment technology, and treating pollutants at the source to achieve clean production. For example, valuable metals such as cobalt and nickel in waste lithium-ion batteries can be effectively recovered at high temperatures, while reducing environmental pollution.

5. Research and development of new energy materials
In the fields of scientific research and teaching, multi temperature zone rotary furnaces are important experimental equipment that support the research and development of new materials and processes. For example, by adjusting the temperature, atmosphere, and other parameters of a multi zone rotary furnace, the synthesis mechanism and performance evolution of new energy materials under different conditions can be studied, providing experimental basis for innovation in new energy technology.

6. Technical advantages of multi temperature zone rotary furnace
Temperature uniformity: The rotating function of the multi temperature zone rotary furnace enables the material to roll uniformly inside the furnace, achieving uniform heating and homogenization treatment, effectively avoiding the problem of local overheating or underheating of the material.
Atmosphere control: The multi zone rotary furnace can be equipped with a gas supply system, which can provide inert gas or other specific gas environment according to process requirements, prevent material oxidation or reduction, and ensure the purity and performance of materials.
Multi stage heating: Multi temperature zone rotary furnaces are usually divided into preheating zone, sintering zone, and cooling zone. Through multi-stage heating, temperature control is achieved at different stages to ensure the ideal sintering state of new energy materials.
Intelligent control: Multi temperature zone rotary furnaces are often equipped with PLC control systems to achieve automatic control of parameters such as kiln speed, temperature, and atmosphere, improving production efficiency and product quality.
