Application of air compressor in lithium battery production
Lithium battery production industry background
Lithium batteries are the core power source of the modern new energy industry, and their production process places extremely high requirements on the cleanliness and stability of compressed air. Compressed air plays an important role in many key aspects of lithium battery production, including electrode preparation, liquid injection, drying, etc. According to compressed air purity rating standards ISO 8573-1:2010The purity requirements for compressed air for lithium battery production are as follows:
- oil content：<0.01ppm
- dust content：<0.01μm
- dew point：≤-40℃（PDP）
- exhaust pressure：0.8-0.85MPa
Shanghai Granklin Group’s oil-free compression technology, combined with Germany Tüv “0” level oil-free certification, has become the core equipment to ensure the quality of lithium battery production.
Why does lithium battery production require high-quality air compressors
- prevent product contamination
- Residual oil will lead to a decrease in the purity of electrode materials and affect battery performance and safety. ISO 8573-1:2010 Class 1 It is clearly stipulated that the oil content of compressed air used for lithium battery production must be <0.01ppm. Only oil-free air compressors can achieve this goal through the system’s pollution-free certification.
- Ensure equipment reliability
- Oil mist can block pneumatic conveying pipes and stirrers, causing equipment failure. Oil-free technology extends equipment life to 10,000 hours Above, annual maintenance costs are reduced 40%。
- compliance requirements
- Lithium battery production must meet strict safety and environmental protection standards. As a key process medium, compressed air must pass environmental management system certification to ensure no pollution.
- energy consumption optimization
- Permanent magnet frequency conversion technology combined with oil-free compression reduces energy consumption compared to traditional models 18%-25%, passed ISO 50001 Energy Management System Certification。
Selection of core parameters
according to ISO 8573-1:2010 Class 1 In line with lithium battery industry specifications, the following parameters need to be verified:
| parameters | standard requirements | Certification support |
|---|---|---|
| oil content | <0.01ppm (laser online monitoring) | Germany Tüv “0” oil-free certification |
| dew point control | -40℃（PDP）±2℃ | quality management system certification |
| dust content | 0.01μm (H13 HEPA filter) | Product quality and safety certification certificate |
| pressure stability | ≤0.5%FS（0.8-0.85MPa） | EU CE certification |
| corrosion resistance rating | ≥IP55 (workshop humidity 80%) | environmental management system certification |
Potential risks of not using high-quality air compressors
- Product pollution loss
- Oil content causes a decrease in the purity of electrode materials, and the loss of single batch scrapping is excessive. 1 million yuan。
- equipment failure
- Oil coking blocks pneumatic conveying pipes (maintenance costs increase annually 500,000 Yuan）。
- Certification fails
- Failure to pass the safety and environmental protection review will lead to loss of production license qualifications.
- legal accountability
- Violation of the Lithium Battery Safety Standards art. 44, facing annual revenue 2% the fine.
Economic benefits of using high-quality air compressors
| Income dimension | quantitative indicators | Certification support |
|---|---|---|
| Direct cost reduction | Annual electricity savings for 75kW models 220,000 Yuan | ISO 50001 energy management system |
| Improved yield | Battery pass rate +2.5% | quality management system certification |
| Maintenance cost optimization | Reduced frequency of filter replacement 65% | environmental management system certification |
| Carbon trading earnings | Annual carbon reduction 180 tons(Value 210,000 Yuan） | ISO 14064 certification |
Comparison of oilless compressor versus oilless compressor in lithium battery production
| parameters | oil-free compressor | Oiled compressor |
|---|---|---|
| oil content | <0.01ppm (real-time monitoring) | ≥0.01ppm (requires three-level filtration) |
| dew point stability | -40℃±2℃ (smart adsorption system) | -10℃±5℃ (oil interference adsorbent) |
| Average annual maintenance cost | 180,000 – 250,000 yuan | 500,000 – 800,000 yuan(Oil filter replaced) |
| equipment life | 10-12 years(Fully enclosed design) | 5-7 years(Caused by oil pollution corrosion) |
| compliance of | CE/Tüv/ISO certification | Only meets basic industrial safety certification |
