The battery is the heart of an electric car. It decides how far the car goes, how fast it charges, how long it lasts and much of what it costs. Battery technology has moved quickly, and several common beliefs about EV batteries are now out of date.
The two main chemistries
Almost all EVs use lithium-ion batteries, in two main flavors:
- NMC (nickel manganese cobalt). These pack more energy into the same weight, which means longer range, but they cost more and depend on nickel and cobalt.
- LFP (lithium iron phosphate). These are cheaper, safer and very long-lived, with no nickel or cobalt, but they are somewhat heavier for the same range. LFP became the most common EV battery worldwide in 2025, at over half of the market, and more than 80% of EVs sold in China use it.
Myths vs. reality
- “The battery wears out after a few years.” Real-world data from large fleets shows most EV batteries lose capacity slowly, typically keeping most of their range well past 100,000 miles. Carmakers commonly warrant the battery for 8 years or 100,000 miles. LFP cells can handle thousands of full charge cycles.
- “Batteries are too expensive.” BloombergNEF’s 2025 survey found average battery pack prices fell to a record low of $108 per kWh, and about $99 per kWh for EV packs. LFP packs averaged about $81 per kWh. In 2010 the figure was well over $1,000.
- “Cold ruins them.” Cold weather temporarily cuts range and slows charging, but a car’s thermal management system protects the battery. Heat pumps in newer EVs reduce the winter range loss.
What’s coming
- Sodium-ion. These batteries use abundant sodium instead of lithium. They hold less energy, but they’re cheaper and perform better in the cold. CATL began mass-producing its Naxtra sodium-ion cells in late 2025, and the first sodium-ion passenger cars are appearing in China.
- Solid-state. These replace the liquid electrolyte with a solid, promising more range, faster charging and better safety. QuantumScape (with Volkswagen) opened a pilot production line in 2026, and Toyota plans small-scale production from around 2026–2028. Mass-market solid-state cars are still a few years off.
- Recycling. This is already recovering lithium, nickel and cobalt from old packs, and it will matter more as the first big wave of EVs retires. Used EV batteries are also being repurposed for stationary storage.
Where the materials come from
- Lithium is mined mostly in Australia, Chile and China.
- Cobalt comes mostly from the Democratic Republic of Congo.
- Nickel comes increasingly from Indonesia.
- Refining is dominated by China. See The Changing Geopolitics of Renewables.
Mining conditions, especially for cobalt, remain a real concern. That is one reason cobalt-free LFP has grown so fast.
