Key points
- LFP batteries deliver about one-third less driving range than NMC batteries, with energy densities of 170-220 Wh/kg compared to 250-350 Wh/kg.
- LFP cells vent combustible gases when thermally stressed, requiring heavier pack designs that prevent weight savings; an LFP fire in Beijing killed two firefighters when vented gases exploded.
- NMC’s latest chemistry variant (NMC811) now costs nearly the same as LFP, closing the price gap that had driven LFP adoption.
- China owns over 100,000 LFP implementation patents, and new IRA rules restrict federal credits for vehicles using LFP cells where Chinese entities hold 25 percent or more ownership.
