The production and manufacturing of lithium-ion batteries is a process composed of multiple closely connected process steps. Overall, the production process of lithium batteries includes key steps such as electrode manufacturing, battery assembly, followed by injection, sealing, formation, and aging. In these stages, each process contains several key process steps that collectively determine the final performance of the battery.
In the production process of lithium batteries, nitrogen plays a crucial role and almost runs through the entire manufacturing process. The main function of nitrogen is to prevent oxidation, especially during the preparation and assembly stages of positive electrode materials. It can effectively isolate the material from oxygen and moisture in the air, thereby ensuring the stability of battery positive electrode materials. By replacing oxygen in the air, nitrogen provides a stable atmosphere for the coating area, significantly reducing issues such as electrical performance degradation, electrical loss, and capacity decay caused by air infiltration. In addition, nitrogen can also protect the coating agent from oxidation during the coating process, thereby improving the coating quality. The flow rate of nitrogen injected at the inlet of the coating area should be controlled within an appropriate range to ensure that the nitrogen concentration in the coating area is maintained at around 7-10%, and the nitrogen concentration should be continuously monitored. The key process stages involved include positive/negative electrode material pulping, coating, and lamination.
Nitrogen controlled reaction environment in coating process
Inside a lithium battery, the anode and cathode are separated, and when lithium ions move between the two poles of the battery, a series of chemical reactions are triggered. However, if these reactions are affected by impurities such as oxygen, they may impair the performance of the battery. In order to ensure the stability and durability of the battery, nitrogen is introduced to eliminate oxygen, thereby reducing the reaction probability between lithium ions and oxygen. This key process segment covers stages such as primary/secondary injection, chemical transformation, and aging.
The vacuum and atmosphere protection effect of nitrogen
Sputtering coating is a crucial process in the production process of lithium batteries. This process aims to further enhance the performance of the battery by depositing a thin film on the surface of the battery electrode. And nitrogen, as a commonly used protective gas, plays an indispensable role in this process. It can create a suitable vacuum or inert atmosphere to ensure the stability of the sputtering process and product quality.
The battery cleaning function of nitrogen gas
In the production process of lithium batteries, nitrogen is not only crucial for sputtering coating technology, but also widely used in the cleaning process of battery shells and components. By using nitrogen, impurities and residues that may damage battery performance can be effectively removed, ensuring the purity and flawlessness inside the battery and laying a solid foundation for the manufacturing of high-quality batteries.

The baking and dehydration effect of 0 nitrogen gas
The nitrogen baking process plays a crucial role in the battery manufacturing process. Through this process, humidity can be effectively controlled and residual moisture can be reduced. Moisture is a potential threat to battery performance and lifespan, and nitrogen baking can efficiently remove moisture from humid environments, ensuring the quality and stability of batteries.
The Anti Oxidation Effect of Nitrogen in Welding
In the manufacturing process of lithium batteries, nitrogen plays an indispensable role, especially in the welding of positive/negative electrode flash plates, electrode lugs, inlet welding, sealing welding, and welding of battery casings. Nitrogen can effectively prevent metal oxidation and discoloration during the welding process, thereby ensuring the stability and safety of welding. In addition, nitrogen also plays an important role in the use of lithium batteries.
The preventive effect of nitrogen on thermal runaway
In the practical application of lithium batteries, nitrogen is widely used for filling the interior of the battery. Its function is to build a protective barrier aimed at preventing oxidation reactions and thermal runaway within the battery. Through this approach, the safety of lithium batteries has been significantly improved, thereby reducing the likelihood of accidents occurring.
Application of Nitrogen in Extending the Life of Lithium Batteries
The application of lithium batteries in automobiles is becoming increasingly widespread, and nitrogen, as an important protective gas, plays a key role in extending the life of lithium batteries. Due to the continuous movement of lithium ions between the positive and negative electrodes during the use of lithium batteries, the battery capacity gradually decreases. However, by introducing nitrogen, we can effectively slow down the rate of capacity decay. Nitrogen can reduce the oxidation reaction inside the battery, thereby reducing the degree of corrosion and damage to the battery. At the same time, it can also regulate the temperature changes inside the battery, further delaying the aging and damage of the battery. Therefore, the rational use of nitrogen is of great significance for improving the lifespan of automotive lithium batteries.

The role of zero nitrogen in improving the performance of lithium batteries
In the application of lithium batteries, nitrogen plays an important role. It can regulate the pressure and temperature inside the battery, thereby increasing the output power and energy density of the battery. In addition, nitrogen can effectively reduce the internal resistance of the battery, thereby improving the efficiency and stability of the battery. In summary, nitrogen plays multiple roles in the production of lithium battery materials, including controlling the reaction environment, protecting materials, and enhancing the redox properties of material surfaces. At the same time, nitrogen is widely used in the testing, evaluation, and use of batteries to improve their stability and safety. With the continuous innovation of battery technology, the application of nitrogen in battery material production will become increasingly indispensable.
