Lithium iron phosphate batteries and 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.

Lithium iron phosphate batteries (energy) and Vehicles, ships, rail, aircraft (industry): 5 relationships.

How they are linked

1. Traction batteries

Physical flow · Strong · Lithium iron phosphate batteries → vehicles

The battery is the costliest part of an electric vehicle, and LFP cells are the default choice for cheaper cars, buses, three-wheelers and many trucks; the site rates LFP 5 of 5 for EV battery cell and materials makers, for whom it is the core product.

over 55% LFP share of EV batteries deployed worldwide, 2025, up from nearly 50% in 2024
1.2 TWh EV battery deployment, 2025
5 of 5 site criticality for EV battery cell and materials makers

LFP stores less energy per kilogram than nickel-rich cells, so it suits vehicles where cost, safety and cycle life matter more than range. Adoption is uneven: deployment is heavily concentrated in China, LFP was more than 10% of EU EV battery demand in 2025, similar to 2024, and its US share almost halved in 2025 from an already low base.

2. Cheaper cells, cheaper EVs

Cost and price · Strong · LFP cell costs → EV prices

LFP uses iron and phosphate instead of nickel and cobalt, so its packs cost much less per kWh, and that saving passes into the price of the vehicle.

more than 40% average cost advantage of LFP packs over NMC packs per kWh, 2025
8% fall in average battery prices, 2025
30% gap between battery pack prices in China and North America, 2025

Part of the measured cost gap reflects LFP's use in stationary storage, where energy density matters less. Pack prices in China were 30% below North America in 2025, an advantage for vehicle makers that build or buy there.

3. Vehicle demand sets cell output

Transition · Rising · EV and electric truck sales → LFP demand

Vehicles take most lithium-ion battery output, so EV sales growth, and the shift of heavy vehicles to batteries, drives LFP plant investment.

almost 3 TWh expected EV battery deployment by 2030
about 8% electric trucks' share of EV battery deployment, 2025, up from under 5% in 2024

Trucks need large, long-lived packs that suit LFP, so their growth adds to LFP demand faster than vehicle numbers suggest. Sodium-ion is a possible competitor for low-cost vehicles, but its cell capacity is just over 1% of lithium-ion capacity and its energy density is lower.

4. Chinese supply chain

Shared risk · Strong · Chinese LFP cathode and cell output → vehicle makers elsewhere

LFP cathode materials and their precursors are made almost entirely in China, and China makes most cells, so vehicle makers elsewhere that want LFP depend on Chinese supply or licences.

over 80% China's share of battery production, 2025

This concentration means trade measures on Chinese batteries raise the cost of the cheapest EV chemistry outside China. Building LFP cathode and cell plants elsewhere is the main response, but it takes years.

5. India's cell PLI

Policy · High in India · India's ACC PLI scheme → domestic cells for vehicles

India imports nearly all its battery cells, so its production-linked incentive for advanced chemistry cells aims to build local capacity that vehicle makers can buy from.

50 GWh cell capacity targeted by 2025 under the ₹18,100 crore ACC PLI scheme
1.4 GWh capacity commissioned on time by October 2025, about 2.8% of target

Demanding local-content rules, a compressed two-year installation window and visa delays for Chinese technical experts slowed the scheme; the 1.4 GWh commissioned on time was all Ola Electric's, and no incentives had been paid by January 2026. Indian vehicle makers therefore still rely on imported cells.

For investors

Key learnings

LFP is now the majority EV battery chemistry, over 55% in 2025, driven by a cost advantage of more than 40% over NMC packs.
The LFP supply chain is concentrated in China, so trade policy decides whether non-Chinese automakers can use the cheapest chemistry.
Electric trucks are a fast-growing LFP market, about 8% of EV battery deployment in 2025.

For policymakers

Key learnings

India's EV makers rely on imported cells, close to 100% in January 2026, so cell supply is a strategic dependency for the vehicle industry.
The ACC PLI commissioned only 1.4 GWh of its 50 GWh target on time, which shows that demanding local-content rules and short timelines can slow plants.
LFP's low cost suits price-sensitive vehicle segments, so local LFP cathode and cell capacity matters for affordable Indian EVs.

What to track

ACC PLI capacity commissioned: Progress towards domestic cell supply (Quarterly · Ministry of Heavy Industries)
Lithium-ion cell imports by source: Dependence on Chinese cells (Monthly · DGCI&S)

India

India's reliance on imported battery cells was still close to 100% in January 2026, and its ₹18,100 crore cell PLI had commissioned only 1.4 GWh of a 50 GWh target on time, so Indian EVs mostly run on imported cells.
