China has just put the first mass-produced sodium-ion electric car on the road, and its most disruptive feature is not price or range but how calmly it shrugs off brutal cold. In early tests, the Changan model using a new sodium chemistry keeps close to its rated 248-mile range even when the thermometer plunges, a scenario that can slash conventional lithium packs by a third or more. That single advantage, reliable winter performance, could quietly redraw the EV adoption map in the snowbelt long before sodium cells match lithium on every spec sheet.
Instead of trying to dethrone lithium overnight, sodium-ion looks set to open a second front in the battery race: cheaper, safer packs for mainstream cars that must work in real-world weather, not just lab conditions. If that plays out, I expect sodium-powered models to expand EV uptake fastest in sub-zero regions where today’s drivers still treat winter as a season of range roulette.
The car that turned “table salt” into a drivetrain
The breakthrough vehicle comes from China, where automaker Changan Automobile and battery giant CATL have jointly launched what they describe as the world’s first mass-produced sodium-ion EV with a quoted 248-mile range. The project is part of a broader national push in China to diversify beyond lithium, and it moves sodium cells from lab demos into a showroom-ready passenger car. Reporting on the launch notes that Chinese battery giant CATL is supplying the pack while Changan integrates it into a compact crossover aimed at everyday buyers rather than early adopters.
What makes this car more than a curiosity is that Changan will be the first company to put a sodium-ion battery into a production EV that ordinary drivers can buy, not just test on a track. Coverage of the launch stresses that Changan is positioning the model as a practical family car, not a halo product. That choice matters: it signals that sodium is being treated as a workhorse chemistry suited to mass-market transport, much as LFP cells quietly became the backbone of budget and fleet EVs.
Why sodium shrugs off the cold where lithium sags
The crucial edge for sodium-ion is how it behaves when temperatures plunge. In controlled testing, CATL’s sodium pack reportedly retains 90% of its capacity at 40°C, a temperature where many lithium-ion packs see their usable energy plunge and charging speeds throttled. Separate descriptions of the chemistry highlight that these sodium cells are designed to remain stable down to Earth-chilling conditions of minus 40 degrees, a range that aligns with earlier sodium-powered train projects that already operate in harsh climates.
That performance is not a minor comfort feature, it is a structural fix for one of the biggest psychological barriers to EV ownership in cold regions. Analyses of battery chemistries note that sodium-ion cells are inherently more tolerant of low temperatures and can be engineered to operate across a wide window from roughly minus 40 to plus 40°C, while many lithium chemistries require heavy thermal management to avoid damage or severe range loss. When drivers in Canada, Scandinavia or northern China can expect their winter commute to feel much like their summer one, the perceived risk of going electric drops sharply.
Abundant sodium, strained lithium and the cost question
Behind the scenes, the sodium story is also about geopolitics and supply chains. Battery researchers point out that Sodium is roughly 1000 times more abundant than lithium in the Earth’s crust, which means producers can tap far more geographically diverse sources, from seawater to common mineral deposits. That abundance gives countries outside the current lithium triangle a clearer path into the battery value chain and reduces the leverage of a few mining regions over global EV production.
Industry comparisons of Electric chemistries also stress that sodium packs can avoid nickel and cobalt entirely, cutting both cost and the ethical baggage tied to those metals. Early commentary from battery makers such as CATL frames sodium as “much cheaper than lithium” at scale, although detailed pack-level cost data for the Changan car has not yet been disclosed. The strategic implication is clear enough: if sodium cells can undercut lithium on price while offering acceptable range, they could become the default for budget EVs and stationary storage, leaving high-end performance models to chase ever denser lithium chemistries.
Inside the “dual chemistry” strategy
One of the more intriguing details is that Changan Automobile and CATL are not betting on sodium alone. Reporting on the launch describes a Forget “dual chemistry” approach that pairs sodium-ion cells with LFP modules in the same vehicle, using software to orchestrate which pack handles which load. In that setup, sodium can take the brunt of cold-weather operation and frequent fast charging, while LFP contributes extra energy density for longer trips in milder conditions. It is a hybridization of chemistries rather than powertrains, and it hints at how automakers may mix and match cell types to tailor cars for specific climates and use cases.
This strategy also undercuts a common assumption in early coverage that sodium must fully replace LFP or nickel-rich lithium cells to matter. By treating sodium as a specialist within a broader battery system, Changan and LFP suppliers can smooth over sodium’s lower energy density while still harvesting its cold-weather and cost advantages. I expect other manufacturers to copy this playbook, especially for crossovers and small SUVs that must serve as both city runabouts and long-distance family cars.
From lab trains to family cars
Sodium batteries have already proven they can power real vehicles, just not ones most people drive. A few years ago, a passenger train equipped with sodium-ion packs began running regular routes, with engineers emphasizing that it was not a prototype but a working part of the rail network. That project demonstrated that sodium cells could handle repeated charge cycles, regenerative braking and the thermal swings of outdoor operation, albeit in a platform with far more space and weight allowance than a compact car.
The Changan launch effectively miniaturizes that proof of concept into a consumer product. Descriptions of the new EV highlight that it sits within the broader category of Hybrid and electric vehicles that Chinese brands are rapidly scaling for export. The move from trains to family cars suggests that sodium’s engineering challenges, from cell packaging to battery management software, are now far enough along to support mass production, even if long-term degradation data over 100,000 miles is still unverified based on available sources.
