Lithium-ion battery cells

Description

1. Key Specifications & Technical Characteristics

• Chemical composition: NCM 811 (LiNi₀.₈Co₀.₁Mn₀.₁O₂) cathode / graphite-silicon composite anode

• Purity level: Transition metal impurities <20 ppm; moisture content <50 ppm

• Physical characteristics: Prismatic or cylindrical form factor; nominal voltage 3.6–3.7V; cell weight 280–320g (depending on capacity); density 2.5–2.6 g/cm³

• Packaging options: Vacuum-sealed aluminum laminated pouches or rigid steel cases; shipped in UN-certified insulated cartons with flame-retardant separators

• Shelf life: 12 months at 30% SOC, 25°C storage; capacity retention ≥90%

2. Core Industrial Applications

• Electric vehicle OEMs: Battery pack assembly for passenger cars, buses, and LCVs – outperforms LFP in cold-weather discharge (85% capacity at -20°C vs. 70% for LFP)

• Stationary energy storage: Solar/wind peak shaving and backup power – achieves 94% round-trip efficiency, lowering LCOE by 18% compared to lead-acid alternatives

• Industrial robotics & AGVs: High-rate discharge (3C continuous, 5C pulse) enables faster cycle times and 30% longer run-time per charge than standard NMC cells

• Marine & heavy equipment: Vibration-resistant design (ISO 12405-3 certified) reduces failure rates in high-shock environments by 40%

3. Competitive Advantages

• Quality consistency: ±1.5% cell-to-capacity variance across production lots; 100% electrical and leakage testing prior to dispatch

• Supply reliability: Three vertically integrated production lines with 500 MWh/month capacity; average on-time delivery >97% over 24 months

• Logistics capability: UN38.3-certified, DG-ready packaging; available for expedited air freight (72-hour emergency fulfillment) or sea freight (FOB major Asian ports)

• Price competitiveness: Tier-1 performance at 8–12% below European/Korean equivalents for volumes >5,000 cells

• Sustainability: RoHS-compliant; cobalt sourced from audited, conflict-free supply chains; cell-to-pack recyclability >70%

• Technical support: Full data sheet, MSDS, batch test reports, and application engineering support included with initial order

4. Commercial & Supply Information

• Minimum order quantity (MOQ): 5,000 cells (sample evaluation kits available at 50 cells)

• Bulk 20MT loading capacity: Approx. 62,000 prismatic cells (based on 321g average cell weight) per 20FT container

• Loading capacity per 20FT container: 20 metric tons net cell weight, with packaging materials adding ≤5% tare weight
