Specialized Nitrogen Generator For Application Of Nitrogen In Lithium/ Sodium New Energy Industry

Application of Nitrogen in Lithium/Sodium New Energy Industry

Atmosphere control: Nitrogen can be used to create an oxygen free or low oxygen atmosphere to prevent unnecessary reactions between highly reactive materials in lithium batteries and oxygen, thereby improving the safety and stability of the battery.

Redox reaction: Some lithium battery manufacturing processes require nitrogen gas as part of the reaction atmosphere to promote the redox reaction, such as the synthesis and modification of positive and negative electrode materials.

Protective materials: During the assembly process of lithium batteries, nitrogen can also be used as a protective gas to prevent the electrolyte and other components in the battery from being contaminated by moisture and oxygen, thereby extending the battery's lifespan.

Cleaning and removal of impurities: Nitrogen can also be used to clean the surface of battery components, removing impurities or residues that may have a negative impact on battery performance.

In summary, nitrogen plays multiple key roles in lithium battery production, including maintaining anaerobic environments, promoting reactions, protecting materials, and cleaning processes. These applications help ensure the performance, safety, and stability of lithium batteries, therefore nitrogen plays an important role in the lithium battery industry. In lithium battery production, industrial grade nitrogen gas (99% to 99.9% purity) is typically used to maintain an oxygen free or low oxygen environment to ensure that the preparation process of battery components is not affected by oxygen interference. However, the specific nitrogen purity requirements may vary depending on the manufacturing process and battery type.

When the air in the pressurized through the purification and drying, Base on Aerodynamics, nitrogen and oxygen in the air in the zeolite molecular sieve (ZMS) on the Pressure swing adsorption  will performance of different diffusion rate through the adsorption of nitrogen. Oxygen in carbon molecular sieve on the surface of the diffusion rate is higher than nitrogen. When the adsorption was not in balance, oxygen was absorbed by carbon molecular sieve in large quantity, and nitrogen was concentrated and enriched in the gas phase to achieve separation of oxygen and nitrogen.
