Key Features

1. Premium Energy Density

5,000mAh (18.5Wh) Nominal Capacity – Highest mass-produced capacity in 21700 format, achieving ≥250Wh/kg energy density.
Ultra-Flat Discharge Curve: Maintains >3.5V throughout 90% of discharge (0.2C rate), maximizing usable energy.

2. Optimized Longevity & Consistency

1,000+ Cycles (to 80% capacity @ 0.5C/0.5C, 25°C) – 2× longer cycle life vs. entry-tier 21700 cells.
Batch Consistency: <0.5% capacity variance (A-grade sorting), critical for multi-cell packs.

3. Advanced Safety Engineering

Dual-Protection Core: Integrated CID + PTC with ceramic-reinforced separator (150°C shutdown).
UN38.3 & IEC 62133 Certified: Passes overcharge (10V), short-circuit (<80°C surface temp), and crush tests.

4. Wide-Temperature Performance

-30°C to 60°C Operating Range: Retains >65% capacity at -20°C (0.2C discharge).
Low Self-Discharge: <3%/month storage loss (vs. 5-8% for LFP alternatives).

5. Eco-Conscious Compliance

RoHS/REACH/CP65 Certified: 0% cadmium, mercury, or PFAS.
Carbon Footprint Tracking: LG’s blockchain-enabled supply chain transparency.
