What are the applications of customized rotary tube furnaces with multiple temperature zones in the field of new energy?

The application of customized rotary tube furnaces with multiple temperature zones in the field of new energy is extensive and in-depth, mainly reflected in the following aspects:

1. Preparation and Performance Optimization of Battery Materials
Lithium Ion Battery Materials
Positive electrode material: By controlling the temperature in multiple temperature zones (such as preheating zone at 600 ℃, sintering zone at 1150 ℃, cooling zone at 300 ℃) and protecting with an inert atmosphere (such as argon gas), ternary materials, lithium iron phosphate and other positive electrode materials are prepared to improve material crystallinity and cycle life.
Negative electrode material: Achieve uniform heat treatment of negative electrode materials such as graphite and silicon-based materials during rotation, prevent particle agglomeration, and improve the energy density and stability of the battery.
Performance testing: Simulate temperature changes in the actual working environment of batteries, evaluate the charging and discharging performance, cycle stability, etc. of materials at different temperatures, and provide data support for material improvement.
Sodium ion battery materials
Similar to lithium-ion batteries, multi temperature zone rotary tube furnaces can be used for the preparation and performance testing of positive and negative electrode materials for sodium ion batteries, promoting the development and application of sodium ion battery technology.
Solid state battery materials
In the heat treatment process of solid-state battery materials, the multi temperature zone design can achieve gradient heating, avoiding material cracking due to uneven temperature, while the rotation function promotes uniform contact between the solid-state electrolyte and the electrode material, improving battery performance.

2. Synthesis and activation of fuel cell materials
Catalyst Preparation
In a hydrogen atmosphere, high activity fuel cell catalysts (such as Pt/C) are prepared by multi temperature control (such as low-temperature reduction and high-temperature activation) to improve catalytic efficiency and service life.
Synthesis of electrolyte materials
Utilizing the high-temperature uniformity of a multi zone rotating tube furnace, solid-state electrolyte materials required for proton exchange membrane fuel cells (PEMFCs) are synthesized to ensure material purity and ion conductivity.

3. Innovative preparation of solar cell materials
Negative electrode material for silicon-based solar cells
By using ultrafast Joule heating technology to control the thermal interaction between carbon and silicon phases, a silicon carbide “rivet point” is formed to solve the phase separation problem in traditional heat treatment, ensuring a strong bond between graphene and silicon and improving battery conversion efficiency.
Perovskite solar cell materials
Step by step annealing of perovskite films in a multi temperature zone environment, reducing film defects through precise temperature gradient control, and improving device stability and optoelectronic performance.

4. Rapid synthesis and performance improvement of energy storage materials
Electrode materials for supercapacitors
By utilizing high-temperature thermal shock strategy, carbon based electrode materials with high specific surface area can be rapidly synthesized in a short period of time to enhance the energy density and power density of supercapacitors.
Lithium sulfur battery materials
By uniformly heating and controlling the atmosphere in a multi zone rotating tube furnace, the sulfur positive electrode material can be uniformly loaded and a conductive network can be constructed to suppress the “shuttle effect” and improve the battery cycle life.

5. Recycling and Regeneration of Waste Battery Materials
Lithium ion battery recycling
Effective recovery of valuable metals (such as cobalt, nickel, and lithium) from waste lithium-ion batteries is achieved through heat treatment technology in a rotary tube furnace, while source control of pollutants is carried out to achieve clean production.
Fuel cell catalyst regeneration
Perform high-temperature reduction treatment on deactivated fuel cell catalysts to restore their active sites, prolong their service life, and reduce usage costs.

6. Basic research and development of new energy materials
Research on the Mechanism of Material Synthesis
By utilizing the high-precision temperature control and atmosphere control capabilities of a multi zone rotating tube furnace, the mechanisms of phase transition and diffusion in the synthesis process of new energy materials are studied, providing theoretical basis for material design.
