Core Manufacturing Capabilities: 3.2V Cylindrical LiFePO4 Excellence

1. 3.2V-Specific LiFePO4 Production

Precision 3.2V Cell Design: Tailored electrode Proportioning (cathode/anode ratio 1:1.05) and electrolyte formulation optimized for 3.2V nominal voltage, ensuring ±0.02V voltage consistency across batches. The 10440 cylindrical format maximizes energy density (1000–1500mAh) while maintaining 3.2V stable discharge curves from 100% to 0% SOC.

LiFePO4 Material Optimization: High-purity LiFePO4 cathodes (≥99.5% purity) and modified graphite anodes specifically selected for 3.2V cylindrical batteries, enhancing ion conductivity and reducing voltage drop during high-rate discharge.

3.2V Cycle Life Enhancement: Proprietary electrode coating technology and electrolyte additives extend 3.2V battery cycle life to 2000+ cycles (80% capacity retention), outperforming standard LiFePO4 cells in long-term 3.2V operation.

Low-Temperature 3.2V Performance: Specialized electrolyte formula enables 3.2V stable discharge at -40°C to 60°C, addressing the low-temperature limitations of conventional LiFePO4 batteries for extreme environment applications.

2. 3.2V Cylindrical-Specific Production Technology

3.2V Precision Winding Process: Customized cylindrical winding equipment with tension control (±0.1N) optimized for 3.2V cell structure, ensuring uniform electrode alignment within the 10440 cylindrical space. This minimizes internal resistance and maximizes 3.2V discharge efficiency.

Hermetic Sealing for 3.2V Stability: Laser welding technology tailored for 3.2V cylindrical battery caps, achieving airtight sealing (leak rate ≤1×10⁻⁶ Pa·m³/s) that prevents electrolyte leakage and moisture ingress—critical for maintaining 3.2V voltage stability over long storage periods.

3.2V Gradient Electrolyte Injection: Temperature-controlled (25±2℃) injection systems with precise dosage control (±0.01ml) for 3.2V cells, ensuring uniform electrolyte distribution across the winding stack. This optimizes 3.2V ion conductivity and reduces self-discharge (≤2%/year at 25℃).

Cylindrical Shell Anti-Corrosion Treatment: High-precision stamping of 304 stainless steel cylindrical casings with nickel-plated coating, enhancing corrosion resistance and structural strength—protecting 3.2V internal components from harsh environments.
