Designed for high-utilization fleets, our NCM 523 pouch cell (5:2:3 ratio) offers 3,500+ cycles at 100% DOD with 80% capacity retention. The 20Ah cell (160x90x5mm) features a manganese-stabilized cathode and hard carbon anode, delivering 180Wh/kg energy density and a self-discharge rate of <2% per month. The UL 94 V-0 certified casing supports fast swaps (90 seconds) via standardized tabs, while pre-heating boosts capacity to 90% at -15°C
Q: What is the recommended storage temperature?
A: 0-25°C with 30-50% SOC to minimize self-discharge.
Q: Can these cells be recycled?
A: Yes, 95% recyclable via our closed-loop program, with cobalt/nickel recovery rates >98%.
