Battery technology, explained

The battery is most of an electric car — its cost, its range, how fast you can recharge and how long the whole thing lasts. Chinese manufacturers now build every major cell chemistry at scale, so the pack under the floor is a real decision, not a footnote. Each chemistry below covers what it is, where it wins and loses, which driving it suits, a predicted lifetime, and exactly which cars in the catalog use it.

How we assign chemistry. A model is tagged with a chemistry only when its manufacturer states that chemistry for that exact car on an official page — never from press releases, supplier names or China-market specs. Today 45 of the 65 battery-equipped models (69%) carry a manufacturer-stated chemistry; the rest are listed honestly as “not published”. Predicted lifetimes are industry cell-cycle estimates, clearly labelled as estimates; each chemistry also shows the contractual battery warranty actually published for the cars using it. Data as of 2026-08-28.

LFP

lithium iron phosphate 26 models

The phosphate cathode replaced nickel and cobalt with iron. It is the chemistry BYD built its Blade Battery around, and the reason LFP went from budget cells to half the European market in five years.

Advantages

  • Materially longer cycle life — commonly rated for 2,000–6,000 full cycles before ~80 % capacity, several times an early NMC cell
  • Thermally the most stable lithium chemistry in mass production: far harder to trigger thermal runaway
  • No nickel or cobalt: cheaper, and free of the cost and ethics exposure of those supply chains
  • Happy at 100 % state of charge — charging to full every night barely costs you life

Trade-offs

  • Lower energy density: roughly 150–180 Wh/kg at cell level versus 200–270 for NMC, so the same range costs more pack mass
  • Cold weather hurts efficiency and charge speed more than NMC unless the pack is preconditioned
  • The density ceiling makes very-long-range packs (100 kWh+) heavier than they need to be

Best for

City and family cars, home-charged daily, high-mileage fleet duty and anyone who plans to keep the car past the warranty — the cycles are there for it.

Predicted lifetime

2,000–6,000 cycles to ~80 % capacity (typical published cell range). At ~350 full-charge-equivalent cycles a year that is well past a 10-year service life — the cell, not the calendar, is rarely the limit. Estimate, not a guarantee.

Published battery warranty on these 26 models: at least 8 yr / 160k km (weakest listed).

Models using LFP

NMC / NCM

nickel manganese cobalt (“ternary”) 8 models

The high-nickel performance chemistry. Where a manufacturer lists maximum range or a large pack in a light body, it is usually an NMC pack underneath.

Advantages

  • The best energy density in mass production: 200–270 Wh/kg, so the longest WLTP range per kilogram of battery
  • Stronger power delivery — the usual choice for performance and fast-charge-focused 800 V cars
  • Cold-weather behaviour noticeably better than LFP

Trade-offs

  • Shorter cycle life — commonly 500–2,000 cycles to ~80 %, and high-nickel cells sit at the lower end
  • Lives harder at 100 %: daily full charges and DC-heavy use measurably accelerate degradation
  • Nickel and cobalt content brings cost, supply-chain and mining-ethics exposure
  • Thermally less stable than LFP (certified packs manage it, but the cell itself is the reason)

Best for

Long-distance flagships, performance models and cars you cannot charge at home — where kilometres per pack kilogram beat cycle-count economics.

Predicted lifetime

500–2,000 cycles to ~80 % capacity (typical published cell range). Charging to 80–90 % on daily duty and preconditioning in winter keeps a modern NMC pack inside its warranty envelope for ~8–12 years. Estimate, not a guarantee.

Published battery warranty on these 8 models: at least 8 yr / 160k km (weakest listed).

Both, by trim

LFP on some trims, NMC on others 11 models

The pragmatic manufacturer answer: one body, two packs. Entry and mid trims carry the cheap, durable LFP cell; the long-range or performance trim gets NMC to chase kilometres.

Advantages

  • You can pick the chemistry that matches your use from the trim list
  • The LFP trims keep the price and durability; the NMC trims keep the headline range

Trade-offs

  • Spec sheets get ambiguous — always check which pack your exact trim carries before ordering
  • Resale value follows chemistry by trim: high-mileage buyers favour the LFP variants

Best for

Shoppers who read the trim table: daily commuters take the LFP grade, long-haul drivers take the NMC grade — same car, same warranty.

Predicted lifetime

Matches the trim: see LFP or NMC. Whatever the trim’s chemistry implies; the published battery warranty below is the contractual floor either way.

Published battery warranty on these 11 models: at least 8 yr / 160k km (weakest listed).

Semi-solid-state

solid-state-adjacent cells 0 models

A solid ceramic-glass electrolyte partially replaces the liquid. Still rare and still premium: if a manufacturer documents it on a car you can order, it is a flagship battery.

Advantages

  • Roughly 300–360 Wh/kg demonstrated in shipping packs — long range without LFP mass
  • Much less flammable electrolyte than conventional cells

Trade-offs

  • Only appears on top-spec packs at flagship prices
  • Field cycle-life data is thin — a few years of public use, not a decade

Best for

Early adopters who want maximum range and are willing to pay a premium for the newest cell science.

Predicted lifetime

Manufacturer cycle data not yet mature — treat published figures as provisional. Where offered, the pack carries the same contractual battery warranty as the rest of the range — check the model page. The honest answer: nobody has a decade of data yet.

Sodium-ion

Na-ion 0 models

Lithium replaced by sodium: cheap, abundant and cold-resistant, but low density — a city-car chemistry, and barely present in Europe’s showrooms so far.

Advantages

  • No lithium, nickel or cobalt: the cheapest raw-material profile in the industry
  • Keeps most of its capacity far below freezing — better winter behaviour than any lithium pack
  • Fast charging tolerance and good thermal safety

Trade-offs

  • Lowest energy density in production (~120–160 Wh/kg): only sensible on small, light cars
  • Cycle life published so far trails good LFP

Best for

Small city cars in cold climates where cost and winter range matter more than outright distance.

Predicted lifetime

~1,000–2,000 cycles claimed by early production cells. Too new for field-verified projections — rely on the contractual warranty and treat vendor cycle claims as first-generation.

Chemistry not published

20 battery-equipped models have a pack size listed by the manufacturer but no stated cell chemistry on any official page we accept as a source. We would rather show you the honest gap than guess: their pages carry the kWh figure and link back here. If your exact trim matters, ask the dealer or configurator which cell supplier and chemistry it ships with.

Reading lifetime on a spec sheet

No manufacturer prints a cell cycle-life number per model, so any “lifetime” claim is an estimate. Two figures are real, though: the energy-density and cycle ranges above are the standard published envelopes for each chemistry (from cell makers like CATL and BYD, echoed across the industry), and the battery warranty under each card is the manufacturer’s own contractual promise on the exact cars — commonly 8 years or 160,000+ km to a minimum state of health. Where those two disagree for a car you are considering, trust the warranty and ask the dealer about the pack.
