Compressed air dew point requirements for battery manufacturing
The requirements for the dew point of compressed air in battery manufacturing are usually very strict, generally below -40 ℃, and some key processes even require -50 ℃ to -60 ℃.. This requirement stems from the extremely high standards of air quality in battery production-any trace of moisture may cause moisture in battery materials and deterioration of electrolyte, which in turn leads to battery performance degradation, shortened life, and even safety hazards.
In battery manufacturing, the dew point control of compressed air is directly related to the humidity management of the production environment. The lower the dew point, the lower the moisture content in the air, and the more it can meet the demand for a dry environment for battery production. For example, in the pole piece drying, liquid injection, sealing and other key processes, the dew point of compressed air should be strictly controlled below -40 ℃ to ensure that the pole piece, electrolyte and other core materials are not affected by moisture.
Water-lubricated air compressor plays an important role in battery manufacturing. It uses water lubrication technology to replace traditional lubricants, eliminating the risk of oil pollution from the source and ensuring the purity of compressed air. At the same time, the water-lubricated air compressor needs to be equipped with efficient drying equipment to further reduce the dew point of compressed air and meet the demand for dry air in battery production.
Specifically, water-lubricated air compressors help battery manufacturing:
- provide pure compressed air: Water lubrication technology avoids the use of lubricating oil, ensures the oil-free characteristics of compressed air, and prevents the pollution of battery materials by oil.
- Reduced dew point: The water-lubricated air compressor is used in conjunction with high-efficiency drying equipment to reduce the dew point of compressed air to below -40°C or even lower, meeting the strict requirements of battery production for dry air.
- stable operation: The water-lubricated air compressor has a simple structure, few parts, and low failure rate. It can run stably for a long time and reduce the impact of downtime and maintenance on production.
- Energy saving and environmental protection: The water-lubricated air compressor can automatically adjust the output according to the actual gas demand through intelligent frequency conversion control, avoiding energy waste and reducing production costs. At the same time, its oil-free design also reduces environmental problems such as waste oil treatment.
