Deployment of batteries for electric vehicles reached 1.2 terawatt-hours in 2025, an almost 30% increase from the previous year and more than seven times the 2020 level, according to the International Energy Agency's Global EV Outlook 2026, which was updated this week.
Electric vehicles now account for more than 70% of total global battery deployment. Lithium iron phosphate (LFP) chemistry crossed 55% of global EV battery deployment in 2025, up from close to 50% in 2024, as lower-cost cells spread beyond China into other markets.
China remained dominant, representing about 60% of global EV battery deployment and more than 80% of manufacturing capacity. In the European Union, LFP made up just over 10% of demand, almost entirely imported from China, while in the United States the LFP share nearly halved as tariffs and tax-credit rules discouraged uptake.
The agency projects global EV battery deployment will approach 3 TWh by 2030, underscoring how quickly the market is scaling even as chemistry and supply chains continue to shift.
