Why is LiFePO4 chemistry preferred for wholesale battery applications in the U.S.?

LiFePO4 (LFP) chemistry dominates wholesale markets due to its safety, longevity, and operational advantages:Thermal Stability: The iron-phosphate cathode resists thermal runaway, reducing fire risks and simplifying pack design.Cycle Life: Quality LFP systems achieve 2,500–8,000 cycles at 70–80% depth of discharge (DOD), outperforming nickel-rich chemistries (NMC/NCA).Flat Voltage Curve: A stable 3.2–3.3V plateau improves state-of-charge (SOC) estimation...
