Safety & Lifespan

LFP resists thermal runaway to ~270 degrees C and lasts 3,000-6,000+ cycles — outliving NMC (~1,000-2,000) by years.

The top 3

1. Thermal Runaway: LFP's Trump Card: LFP stays stable to ~270 degrees C vs ~150-210 for NMC, making it far less likely to ignite when damaged or overcharged.
2. The Cycle-Life Crown: LFP survives 3,000-6,000+ charge cycles vs ~1,000-2,000 for NMC — a decade-plus of daily use before meaningful fade.
3. Cold Weather & the Solid-State Edge: Sodium-ion keeps ~90% capacity at -20 degrees C; solid-state's non-flammable electrolyte promises both safety and long life if it scales.
