What is LFP Battery?
A lithium iron phosphate EV battery chemistry valued for long life, safety and low cost, at the expense of some energy density.
LFP stands for lithium iron phosphate, a battery chemistry increasingly used in electric vehicles. Unlike the nickel-rich chemistries common in long-range EVs, LFP cells use iron and phosphate, which makes them cheaper, more thermally stable and free of cobalt.
The main trade-off is lower energy density, meaning LFP packs are typically heavier or bulkier for a given range. In exchange they offer excellent cycle life, strong resistance to thermal runaway and the ability to be regularly charged to 100 percent without significant degradation.
These characteristics make LFP popular for standard-range EVs, energy storage and any application where cost, safety and longevity matter more than maximum range. Several manufacturers now offer LFP options alongside higher-density chemistries for longer-range variants.
