4th Gen LFP Batteries: What They Mean for Energy Storage Systems
Fourth-generation lithium iron phosphate (LFP) batteries, defined by a compaction density of 2.6 g/cm³ or higher, are hitting the market with energy densities reaching 200-205 Wh/kg. These improvements make LFP increasingly competitive with NMC chemistries for battery energy storage systems (BESS), promising better performance without sacrificing safety or cost advantages.
