Lithium iron phosphate batteries: Relationships

Every element and industry that Lithium iron phosphate batteries is linked to, and how. Each pair has its own card explaining the relationships between the two.

Vehicles, ships, rail, aircraft: Lithium iron phosphate has become the main battery chemistry for electric vehicles, over 55% of EV batteries deployed in 2025, because it is much cheaper than nickel-based cells, but its supply chain is almost entirely Chinese, which shapes where affordable EVs are built.

AC transmission: Grid batteries, now mostly LFP, charge from the transmission grid when power is cheap and feed it back at the evening peak, and India is pushing them with viability gap funding and transmission charge waivers that treat storage as part of the grid. (researched)
Electric and hybrid vehicles: LFP became the most used EV battery chemistry in 2025 because it is the cheapest per kWh, which is what makes low-priced electric cars possible. Almost all of it is made in China, so EV growth in other countries leans on Chinese cells and cathodes. (researched)
Graphite: LFP cells, like other lithium-ion cells, store their lithium in a graphite anode, and with LFP at over 55% of EV batteries in 2025 it is now a major call on graphite. Almost all anode material is made in China, which has used export licensing since December 2023, so graphite is the main supply risk in an otherwise abundant LFP chain. (researched)
Nickel-rich lithium-ion batteries: LFP and NMC are the two main lithium-ion chemistries and compete for every EV and storage project: LFP is cheaper and longer lived, NMC stores more energy per kilogram. LFP passed half of EV batteries in 2024 and over 55% in 2025, while NMC holds premium cars and most markets outside China. (researched)
Phosphate rock: Every LFP cathode needs purified phosphoric acid made from phosphate rock, so the rise of LFP has created a new, high-purity demand that competes with fertiliser for the best rock. The volumes are still small against fertiliser, but they are concentrated in China, which also mines most phosphate. (researched)
Sodium-ion batteries: Sodium-ion cells aim at the same low-cost uses as LFP, storage and small EVs, without needing lithium. Whether they win depends on the lithium price: at the low prices of 2024 and 2025 LFP was very hard to undercut, and the sharp rise in lithium prices in 2026 has improved sodium's case. (researched)
