The high-purity nitrogen generator system for new energy battery production is special precision nitrogen production equipment tailored for lithium battery, power battery and energy storage battery manufacturing processes, which is a key supporting equipment to ensure battery production quality and safety. In the production links of battery electrode coating, winding, assembly, liquid injection and sealing, the production environment is extremely strict with oxygen and moisture content. Oxygen oxidation and moisture erosion will cause battery pole piece deterioration, internal short circuit and capacity attenuation, and even trigger safety accidents such as battery explosion and combustion. Therefore, the new energy battery industry requires nitrogen generators to provide ultra-high purity, low moisture and stable pressure nitrogen supply.

In terms of core performance indicators, the high-purity nitrogen generator for battery production adopts advanced PSA pressure swing adsorption technology and multi-stage purification system, with nitrogen purity stably reaching 99.999% (5N) and ultra-low oxygen content below 10ppm and dew point below -70℃, which fully meets the ultra-dry and ultra-pure gas demand of battery production. The equipment is equipped with a dual-tower adsorption structure and intelligent pressure control system, which can realize 24-hour uninterrupted continuous nitrogen production, with stable output pressure and no fluctuation, avoiding batch quality differences caused by unstable gas supply in battery production. Different from ordinary industrial nitrogen generators, this system adds a special deoxidation and drying purification module to deeply remove trace oxygen and moisture in nitrogen.

In terms of system configuration and safety design, the battery-grade high-purity nitrogen generator system integrates air compression, multi-stage filtration, adsorption separation, deep purification, nitrogen storage and intelligent monitoring systems. The equipment pipeline is made of high-purity stainless steel with strict oil-free and pollution-free treatment to prevent impurity pollution from affecting battery performance. The system is equipped with real-time purity monitoring, pressure monitoring and dew point detection sensors, which can upload operating data to the industrial control platform in real time, automatically alarm and adjust operating parameters when indexes deviate, and realize intelligent unattended operation. In addition, the equipment has overload protection, overpressure relief and emergency shutdown functions to ensure zero safety risk in battery production workshops.

In terms of application value and industry advantages, the high-purity nitrogen system can create an anaerobic and dry production environment for battery manufacturing, effectively prevent pole piece oxidation and electrolyte deterioration, improve battery consistency, cycle life and safety performance. Compared with traditional liquid nitrogen supply methods, the on-site nitrogen generation system has lower operating cost, no liquid nitrogen transportation and storage risks, and continuous and stable gas supply. It is widely used in the whole production chain of power batteries, consumer lithium batteries and energy storage batteries, and has become the standard configuration of modern new energy battery intelligent factories.
