Ultrapure Water Systems for EV Battery Production
Why Lithium Battery Manufacturing Demands Ultrapure Water
• Critical Standard: ≤0.1μS/cm conductivity (18.2 MΩ·cm)
• Key Contaminants Removed:
• Ionic impurities (Na⁺, K⁺, Cl⁻)
• TOC (<5ppb)
• Particles (>0.05μm)
Industry Impact: 1ppm impurities → 15% battery capacity loss (DOE 2023 study)
RO+EDI vs Distillation: Cost Comparison
| Parameter | RO+EDI System | Distillation |
|---|---|---|
| Upfront Cost | $50,000-$200,000 | $300,000+ |
| Operating Cost | $0.3/m³ | $1.8/m³ |
| Energy Use | 3-5kWh/m³ | 80-120kWh/m³ |
| Maintenance | Annual membrane replacement | Weekly descaling |
| Output Quality | 18.2 MΩ·cm | 10-15 MΩ·cm |
ROI Example: 5,000L/h system saves $1.2M/year vs distillation
3-Stage Ultrapure Water Process
1. Pretreatment
• Multi-media filter (SDI<3)
• Double-pass RO (99.5% salt rejection)
• Electrodeionization (EDI)
• Continuous operation
• Zero chemical regeneration
2. Polishing Loop
• UV oxidation (185nm for TOC destruction)
• Submicron filtration (0.05μm absolute)
• Nitrogen blanketing (prevent CO₂ absorption)
3. Monitoring & Control
✔ Real-time resistivity monitoring
✔ Particle counters (ISO 14644 Class 1)
✔ Automated sanitization cycles
