Lithium cells for energy storage (ESS)
Energy-storage pack builders prioritize long cycle life, safety and a low cost per usable kWh. Our 21700 cylindrical cells cover both priorities: NCM energy-storage (E) cells for maximum energy density, and LMFP (manganese-iron-phosphate doped) cells for higher safety and extended cycle life. They suit home storage, solar, telecom backup and commercial ESS.
What matters for storage packs
- Cycle life & safety: LMFP delivers long cycle life with excellent thermal stability, approaching LFP-class safety while keeping better low-temperature performance — for the chemistry background see LiFePO4 vs lead-acid.
- Energy density: NCM energy-type cells maximise usable kWh per module where space and weight are constrained.
- Matched IR & capacity: essential for balanced series/parallel banks.
- Certification: manufacturer cell-safety certificates plus transport documents for your market.
Recommended series
21700 NCM energy type (E) — for example a 50E-class 5000mAh cell rated ≥800 cycles — for energy-dense storage modules, and 21700 LMFP (MF type) where higher safety and longer cycle life are the priority.
