Before You Judge an Electric Car's Range, Ask What Its Battery Is Made Of
Battery size tells you how much energy is stored. Chemistry tells you how it behaves, what it costs and what it needs, and it is printed on a spec sheet most buyers never open.
In short
What happened. Reference sources describe the battery as the part of an electric car that most shapes its cost, range and behaviour in cold weather, and they show that several different chemistries now compete for that job.
What it means. “Battery size” in kilowatt-hours tells you how much energy is stored. The chemistry tells you how the battery behaves, what it costs and which materials it needs.
Risks and impact. The common nickel-manganese-cobalt type is described as sensitive to temperature, and a replacement pack outside warranty is the largest long-term cost uncertainty for owners.
What can be done. Find the chemistry and usable capacity in the spec sheet, and read what the warranty says about the battery.
What to watch. Whether cheaper, mineral-light types such as sodium-ion spread beyond the first mass-production cars reported in 2026.

What happened
An electric vehicle battery is a rechargeable battery that powers the car’s electric motors. Today it is almost always a lithium-ion battery, according to the Wikipedia article on the subject. Compared with liquid fuel, the article says, current batteries hold much less energy for their weight, which either adds weight to the car or cuts its range.
Three chemistries dominate. Lithium nickel manganese cobalt oxide (NMC) became the global standard in the 2010s. Lithium iron phosphate (LFP) is rising and reached 41% global market share by capacity for battery electric vehicles in 2023. Since 2023, LFP has been the leading type in China, while its share in Europe and North America stays below 10%.
Size varies a lot. Available models in 2023 carried between 21 and 123 kWh, with an average of 80 kWh. Demand for electric vehicle batteries exceeded 750 GWh that year.
The same article describes the trade-offs plainly. NMC is “sensitive to temperature” and loses power in the cold; early cells did not accept or supply charge when extremely cold, and heaters can warm them in some climates. LFP has a shorter range but is cheaper, safer and more sustainable, and needs no cobalt or manganese.
Sodium-ion cells avoid critical minerals altogether. The article says Chinese makers began delivering the first models in early 2024 and that by 2026 they are installed in mass-production cars such as the Changan Nevo A06.
What the evidence supports
Here is how the evidence stacks up. All three sources are Wikipedia pages, which are summaries of other publications, not original research. That matters when we weigh each claim.
What the pages agree on: lithium-ion dominates; NMC and LFP are the two main chemistries; LFP trades some range for lower cost and better safety; and the battery is a large share of an electric car’s cost and environmental footprint. The statements are consistent across the pages and match each other.
What rests on a single, weaker footing: the claim that battery costs “fell 87% per kilowatt-hour” in 2019 is introduced with the phrase “was said to have”. We treat it as a reported claim, not a measured fact. The replacement-pack range of $5,000 to $16,000 is likewise a broad estimate that depends on pack size and manufacturer.
What we do not know from these sources: how many kilometres of range a specific car loses at a specific temperature. The pages say cold hurts NMC performance, but they give no percentage, and we will not invent one. The same goes for how long a given pack lasts in everyday use.
If you want a number for your own car, the original studies and the manufacturer’s data are the place to look. These pages are a map, not the territory.
How the story is being framed
The buyer’s view. Most shoppers compare range figures and price. That is sensible, but it hides the chemistry. A cheaper LFP car with a shorter range may suit a commuter who charges nightly; a long-range NMC car may suit someone who drives far and often. Neither is “better” in general.
The sustainability view. The sources note that cobalt mining raises ethical and geopolitical concerns, and that most manufacturing and refining is concentrated in China. LFP and sodium-ion both reduce dependence on those minerals. What this view tends to leave out is that shorter range can mean a bigger or more frequently charged battery for the same use.
The cost-of-ownership view. The Electric car page states that, as of 2020, the total cost of ownership of recent EVs in the United States and European Union was lower than for equivalent petrol cars, thanks to cheaper power and maintenance. That figure is six years old and depends heavily on local electricity and fuel prices. The page also names battery replacement as the largest source of long-term financial uncertainty.
These views do not contradict each other. They answer different questions: what to buy, what it costs the planet, and what it costs you over time.
The background
Electric cars are not new. In the 1890s electric taxis ran in London and New York, and in 1899 an electric car, La Jamais Contente, broke 100 km/h. Petrol cars won because they refuelled faster and were cheaper to make, and the 1912 electric starter motor replaced the laborious and dangerous hand crank.
The modern revival is recent. Tesla’s first Roadster, delivered in 2008, was the first highway-legal electric car with lithium-ion cells and travelled more than 320 km per charge. By 2025, the Electric car page reports, 21 million plug-in electric cars were sold worldwide, over a quarter of new car sales.
Older battery types show why chemistry matters. Lead-acid cars managed up to 130 km per charge. Nickel-metal hydride packs lasted a decade in hybrids but struggled below minus 20 degrees Celsius. The “Zebra” battery, used between 1997 and 2012, was barely affected by cold, but only because it had to be heated to about 270 degrees Celsius to work at all, which cost energy.
Every chemistry is a bargain between energy, safety, cost, lifespan and temperature tolerance. Nothing is free.
The deeper story
A spec sheet is a small act of honesty. It tells you what a thing is made of, and most of us would rather read the headline number.
The same habit shows up far beyond cars. We compare size, price and speed because they are easy to put side by side. Composition is harder: it asks us to learn a few unfamiliar words, and it rarely makes a good advertisement.
There is a quiet lesson in how technology progresses. The older chemistries did not fail; each solved one problem and created another. LFP and sodium-ion look like the next trade, not the end of trading. A reader who understands that will be less surprised by the next headline about a “breakthrough battery”, and less easily sold one.
It also reminds us that cheap and good are not opposites, but they are rarely identical. When something costs less and needs fewer scarce materials, we should ask what was given up, and whether we care about that thing. For some drivers, it is range. For others, it will never matter.
Something to sit with
What do you know about the battery in your own car, or the one you might buy, beyond its size?
When you compare two products, which number are you comparing because it matters, and which because it is printed biggest?
