The application of air compressor in the electric vehicle battery industry mainly includes the following aspects:

1.Compressed air supply in the battery manufacturing process: Compressed air is required in all aspects of battery production, such as stirring, coating, welding protection, liquid injection vacuuming, etc.

2.Oil-free compressed air supply: Due to the high oxidizing properties of lithium metal to water vapor and oxygen, the manufacture of lithium-ion batteries needs to be carried out in an environment with very low water and oxygen concentrations. Oil-free air compressors can provide high-quality compressed air and avoid pollution.

3.Gas supply during battery cooling: In the process of liquid injection and formation of batteries, inert gases such as nitrogen need to be used to form a protective atmosphere to prevent contamination of battery materials.

4.Battery performance test: During the performance test of the battery, the compressed air provided by the air compressor is used to simulate various working conditions that the battery may encounter in actual use.

5.Energy recovery: The heat generated during the operation of the air compressor can be used for building heating or material drying in the battery manufacturing process.

6.On-board air compressors: Air compressors are required for on-board air conditioning, pneumatic braking devices, air suspension and other systems in electric vehicles.

7.Air compressors for fuel cells: In fuel cell electric vehicles, air compressors are used to supply compressed air to the battery stack to improve the reaction efficiency of the fuel cell system.

8.Application of vacuum technology in battery manufacturing: Vacuum technology plays an important role in the process of homogenization, electrode vacuum drying, discs, packaging, liquid injection, and leak detection in battery manufacturing.

Through these applications, air compressors ensure efficient, safe and reliable production processes in the electric vehicle battery industry.
