Who Makes Lithium Iron Phosphate Batteries?
As the demand for safer, more sustainable, and longer-lasting batteries grows across electric vehicles, solar storage systems, and portable electronics, lithium iron phosphate (LiFePO4) batteries have risen to prominence. But who are the leading manufacturers behind this increasingly popular battery chemistry? This article explores the global landscape of LiFePO4 battery production, from major industrial players to specialized innovators.
CATL (Contemporary Amperex Technology Co. Limited)
Headquartered in China, CATL is currently the world’s largest producer of lithium iron phosphate batteries. It supplies prismatic LFP cells to Tesla, particularly for the Model 3 and Model Y Standard Range vehicles manufactured at Giga Shanghai. CATL has:
Advanced manufacturing capabilities for both cylindrical and prismatic formats
A dominant position in EV battery supply chains
R&D leadership in enhancing energy density and cell longevity
CATL’s role has been instrumental in mainstreaming LiFePO4 adoption among top-tier automakers and storage system providers.
BYD (Build Your Dreams)
BYD is not just a car manufacturer but also a major battery producer. Its innovative Blade Battery is a form of lithium iron phosphate cell optimized for space efficiency, thermal stability, and crash resistance. BYD:
Manufactures batteries in-house for its own EVs such as the Han, Dolphin, and Atto 3
Supplies batteries to other automotive companies globally
Has received international recognition for safety due to its non-flammable LFP design
BYD’s vertical integration strategy makes it a powerful player in both EV and stationary storage markets.
EVE Energy
EVE Energy specializes in cylindrical and prismatic LiFePO4 cells for electric mobility, energy storage, and consumer devices. As a core supplier to multiple Chinese EV and energy companies, EVE:
Provides batteries to electric bus manufacturers and solar system integrators
Focuses on high-volume, modular cell production
Has rapidly scaled exports to global markets
EVE’s flexible product line makes it a preferred choice for commercial vehicle and solar storage solutions.
CALB (China Aviation Lithium Battery)
CALB is another major Chinese producer focused on high-performance lithium iron phosphate packs for automotive, aerospace, and grid applications. Known for:
Supplying to state-run bus networks and industrial fleets
Developing EV battery packs with superior cycle life and energy retention
Supporting sustainable transportation initiatives across China and abroad
CALB continues to expand its footprint through global partnerships and production facilities.
Gotion High-Tech
Gotion, headquartered in Hefei, China, is gaining global attention as a supplier of advanced LFP cells, including through a partnership with Volkswagen. It has:
Developed both NMC and LiFePO4 battery chemistries
Plans for U.S.-based manufacturing to serve North American EV markets
Provided batteries for passenger cars, buses, and storage systems
Gotion's international collaborations signal the globalization of LiFePO4 beyond China.
Other Key Manufacturers
In addition to the top five, numerous other companies contribute to LiFePO4 innovation and production:
Farasis Energy: Known for supplying batteries to Daimler and other global clients.
SVOLT: Specializes in cobalt-free battery chemistries including LiFePO4.
LG Energy Solution and Panasonic: Though primarily focused on NMC/NCA, they have begun R&D and pilot production for LFP cells due to market trends.
Global Trends in LiFePO4 Production
The rise of LiFePO4 battery manufacturers is closely tied to growing demand for:
Affordability without sacrificing safety
Renewable energy storage systems
Commercial and public transport electrification
Long-cycle consumer and industrial applications
While China dominates current production, manufacturers in the U.S., Europe, and Southeast Asia are investing in new LFP production lines to meet global needs.
