CATL’s Naxtra is significant because it moves sodium-ion batteries beyond the prototype stage. CATL says the battery is ready for mass production, with a reported 175 Wh/kg passenger-EV cell, more than 10,000 cycles, a claimed 500-kilometer range, and 90% usable power retention at −40°C. Those are CATL-reported specifications—not independently reproduced test results—and they point to sodium-ion as a complement to lithium-ion, not an immediate replacement.
CATL’s Naxtra is important because it moves sodium-ion batteries beyond the prototype stage. At its Super Tech Day on April 21, 2025, CATL said Naxtra was the first sodium-ion battery designed for mass production. The company reported a passenger-EV cell energy density of 175 Wh/kg, more than 10,000 cycles, a claimed 500-kilometer range, and 90% usable power retention at −40°C.

Those are CATL’s specifications, not independently reproduced test results. The announcement does not mean sodium-ion batteries are about to replace lithium-ion across the car market. The more defensible conclusion is narrower and more useful: sodium-ion is becoming a commercially relevant complement to lithium-ion, particularly for cold climates, selected electric vehicles, commercial equipment, hybrid battery packs, and stationary storage.

- A passenger-EV battery using sodium-ion cells.
- A 24-volt integrated start-stop battery for heavy-duty trucks.
CATL described the announcement as the first time sodium-ion battery technology had reached mass production. That wording is significant. Many sodium-ion batteries have previously been demonstrated in laboratories, pilot projects, or limited commercial applications. CATL’s claim concerns industrial production capability rather than merely a promising chemistry or a demonstration vehicle. [C001]
Naxtra is also part of CATL’s broader “multi-power” strategy. Its Freevoy Dual-Power architecture can combine different cell chemistries, including a sodium-ion and lithium-iron-phosphate, or LFP, configuration. In that arrangement, sodium-ion cells can contribute their cold-weather advantages while lithium-ion cells provide higher energy density where range and packaging matter most. [C001]
CATL Naxtra specifications: what the numbers mean
| Claimed characteristic | CATL’s reported figure | Important qualification |
|---|---|---|
| Passenger-EV cell energy density | 175 Wh/kg | A CATL-reported cell figure; it is not the same as whole-pack energy density. |
| Vehicle range | Up to 500 km | CATL’s claim; the announcement does not by itself establish a standardized independent test result. |
| Cycle life | More than 10,000 cycles | Testing conditions and the precise end-of-life definition matter. |
| Operating temperature | −40°C to +70°C | CATL’s stated range for the product. |
| Usable power at −40°C | 90% retention | CATL says usable power remains at 90% in extreme cold. |
| Heavy-truck start-stop battery | More than eight years of service life | Manufacturer claim, not an independently verified fleet result. |
175 Wh/kg is strong for sodium-ion, but not class-leading across batteries
CATL’s 175 Wh/kg claim is near the upper end of current sodium-ion cell performance. However, it remains below the approximate figures cited by the International Energy Agency for leading lithium-ion chemistries: about 205 Wh/kg for LFP and 255 Wh/kg for nickel-manganese-cobalt, or NMC, cells.

A lower-energy-density battery may need to be larger or heavier to provide the same range. That matters in passenger cars, where battery mass, cargo space, aerodynamics, and manufacturing cost all affect efficiency. It is one reason sodium-ion should not be described as universally superior to lithium-ion even if it performs better in a particular cold-weather application.
The reported 500-kilometer range also needs context. Range depends on the vehicle, battery size, aerodynamics, speed, temperature, tires, terrain, and test procedure. CATL’s figure demonstrates the company’s intended capability; it does not establish that every Naxtra-equipped vehicle will travel 500 km in ordinary driving.
Why the −40°C claim matters
Cold-weather performance is the clearest near-term reason to take sodium-ion seriously. Lithium-ion batteries generally lose power and usable capacity as temperatures fall, with LFP cells particularly affected at low temperatures. The IEA says sodium-ion batteries perform significantly better in the cold than lithium-ion alternatives, especially LFP. [C008]
CATL says Naxtra retains 90% of its usable power at −40°C and experiences no significant power degradation at that temperature even when its state of charge is only 10%. [C002] If that performance holds under independently verified operating conditions, it could be valuable for:

- Delivery vans, buses, construction equipment, and other fleets that cannot wait for a battery to warm up.
- Remote equipment and vehicles that may sit outside for long periods.
- Stationary storage exposed to winter conditions.
Cold-weather capability does not mean a sodium-ion vehicle would never need thermal management. It means the chemistry may lose less performance and require less energy or time to remain useful in extreme cold. Real-world results will still depend on the complete pack, its battery-management system, insulation, heating strategy, and the vehicle’s power electronics.
Cycle life and the heavy-truck application
CATL says the passenger-EV Naxtra battery exceeds 10,000 cycles. That could be highly relevant for high-utilization fleets and storage systems, where frequent charging and discharging can matter more than maximum range. But cycle-life comparisons are only meaningful when the test depth of discharge, charging rate, temperature, permitted capacity loss, and calendar-aging period are known.
For heavy-duty trucks, CATL reports that its 24V Naxtra integrated start-stop battery can operate for more than eight years, start at −40°C, and reduce lifecycle cost by 61% compared with traditional lead-acid batteries. [C002] These figures should remain attributed to CATL until fleet data or independent testing shows how the battery performs in actual service.
A start-stop battery is also a different use case from a high-voltage traction battery. It supports vehicle electrical systems and engine starting rather than powering the vehicle for hundreds of kilometers. The truck application therefore demonstrates sodium-ion’s potential in commercial equipment, but it should not be treated as proof of the same economics or performance in every EV.

On February 5, 2026, CATL and Changan announced what they called the world’s first mass-production passenger vehicle equipped with sodium-ion batteries. The companies said market arrival was planned for mid-2026. CATL also said it would supply Naxtra batteries across Changan brands including AVATR, Deepal, Qiyuan, and UNI. [C003]
This is stronger evidence of commercialization than a concept car or a laboratory cell. It connects Naxtra with a vehicle manufacturer, a planned production model, and a stated route to market. But “planned for mid-2026” is not the same as confirmed completed deliveries, and the announcement does not establish availability in the United States or other markets. It also does not provide a consumer price or prove that sodium-ion will be the best battery option for every model.
Why use sodium instead of lithium?
Sodium is much more abundant than lithium, so sodium-ion chemistry could give battery manufacturers another route to reduce direct dependence on lithium resources. CATL presents the technology as a way to improve resource flexibility and energy security. The IEA offers a more cautious assessment: sodium-ion can diversify material supply and reduce exposure to lithium-price volatility, but its manufacturing ecosystem is still far less mature than lithium-ion’s and remains heavily concentrated in China.

That distinction matters. More abundant raw material does not automatically produce a cheaper battery. A battery’s cost depends on its complete bill of materials, cell design, cathode and anode processing, manufacturing scale, equipment, quality control, pack integration, logistics, and supply-chain concentration.
Sodium-ion also does not eliminate every critical-material concern. Depending on the specific chemistry, sodium-ion cells may still use materials such as nickel, manganese, or vanadium. The IEA notes that the industry’s component supply and manufacturing capacity remain concentrated, particularly in China. [C008]
Why sodium-ion is more likely to complement lithium-ion than replace it
The battery industry does not need one chemistry to perform every task equally well. A vehicle optimized for long highway range has different requirements from a city car, a truck’s start-stop system, or a grid battery that cycles every day.
Sodium-ion’s potential advantages include:
- Better low-temperature performance than some lithium-ion alternatives.
- Reduced direct reliance on lithium supply.
- Potentially useful cycle life for high-utilization applications.
- Suitability for applications where size and weight are less important than cost stability, durability, or cold-weather operation.
Its main disadvantages include:
- Lower energy density than leading LFP and NMC cells.
- A less mature manufacturing and supplier ecosystem.
- Continued dependence on some materials that are not entirely free of supply-chain risk.
- No guarantee of lower cost in ordinary markets.
CATL’s dual-chemistry Freevoy approach reflects this trade-off. Instead of forcing sodium-ion to deliver maximum range or lithium-ion to deliver ideal cold-weather performance, the system can assign different jobs to different chemistries. That may prove more practical than a simple battery-chemistry replacement race. [C001]
Is sodium-ion cheaper than lithium-ion?
Not across the board. The IEA says current lithium prices are not yet low enough for sodium-ion to undercut LFP in most applications. Sodium-ion can already be cost-effective in especially cold climates and selected stationary-storage uses, but broad cost leadership has not been established. [C008]
Recommended Free Tools
There are several reasons not to make a blanket “cheaper battery” claim:
- Lower energy density can increase pack requirements. More cells, structure, or physical volume may be needed for a given range.
- Lithium-ion benefits from enormous scale. Its factories, suppliers, engineers, recycling systems, and vehicle platforms are already established.
- Raw-material prices change. Sodium’s abundance is valuable, but lithium prices, production yields, and manufacturing scale influence the final result.
- Application determines value. A battery that is slightly heavier but retains more power in extreme cold may be economically preferable for a northern fleet, even if it is not the cheapest cell in a laboratory comparison.
CATL’s storage plans suggest a broader commercial market
CATL’s sodium-ion push extends beyond passenger vehicles. In an energy-storage announcement in 2026, the company said its mass-production lines were fully commissioned and operational and could support large-scale deployment. CATL said Chinese customer deliveries of sodium-ion storage systems would begin in September 2026, cumulative shipments would reach 1 GWh by the end of 2026, and international deliveries would begin in June 2027.

These are announced delivery plans, not evidence that all of those shipments have already occurred. They do, however, show how CATL is positioning sodium-ion: not only as an experimental automotive chemistry, but also as a product for commercial-scale storage.
CATL also announced a three-year, 60 GWh sodium-ion energy-storage cooperation agreement with HyperStrong in April 2026. The agreement covers technology research and development, product applications, and project deployment. CATL described it as the largest sodium-ion battery supply agreement of its kind at the time of the announcement. [C004]

In July 2026, CATL and Alfen announced a 5 GWh partnership to deploy CATL sodium-ion energy-storage systems across Europe. The companies cited portfolio diversification, resilience against lithium-price volatility, and improved competitiveness in mid-to-large-scale European storage tenders as reasons for the collaboration. [C006]
For grid storage, lower energy density is often less damaging than it is in a car. A stationary battery does not need to carry itself down a highway, and a project developer can sometimes trade land, enclosure size, and cooling requirements against cycle life, temperature performance, supply risk, and total project cost. The economics still depend on the specific project, so these partnerships should be read as evidence of industrial interest—not proof that sodium-ion has already won the storage market.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What “production-ready” does—and does not—mean
CATL’s evidence supports several distinct claims:
- CATL announced a named sodium-ion product family rather than only a laboratory chemistry.
- The company says its mass-production lines are commissioned and operational.
- Changan announced a planned mass-production passenger vehicle using sodium-ion batteries.
- CATL announced large storage partnerships and scheduled delivery plans.
It does not support several broader claims:
- That sodium-ion is already cheaper than lithium-ion in every market.
- That Naxtra’s performance figures have been independently validated.
- That consumers in the United States can currently buy a Naxtra battery through a retail marketplace.
- That every CATL vehicle or storage product will use sodium-ion cells.
- That scheduled deliveries are confirmed completed shipments.
Availability will also vary by geography, vehicle brand, project, and regulatory approval. A production-capable factory is an important prerequisite, but it is only one step between a product announcement and widespread consumer access.

Should drivers be excited about sodium-ion cars?
Drivers in very cold regions have the strongest reason to watch the technology. A sodium-ion car could be attractive if it delivers dependable winter power without requiring a large energy penalty for battery heating. City cars and shorter-range vehicles may also be a natural fit because they do not need to maximize every kilogram of battery mass.

For long-distance EV buyers, the answer is more conditional. A sodium-ion pack may need more mass or volume to provide the same range as a higher-energy-density lithium-ion pack. Whether that trade-off is acceptable will depend on price, charging speed, vehicle design, warranty terms, cold-weather testing, and the actual model’s range—not the chemistry label alone.
For now, buyers should evaluate an individual vehicle’s verified specifications and warranty rather than assume that “sodium-ion” automatically means cheaper, safer, longer-lived, or better in every respect.

CATL’s Naxtra is a meaningful battery-industry milestone because CATL is claiming mass-production capability, not merely demonstrating a sodium-ion prototype. The Changan vehicle announcement, CATL’s storage delivery plans, and its HyperStrong and Alfen partnerships indicate that the chemistry is moving toward real industrial deployment.
But the best conclusion is not that sodium-ion will replace lithium-ion. Its most credible near-term roles are cold-weather mobility, dual-chemistry vehicle packs, commercial equipment, and stationary storage. Lower energy density, an immature and China-concentrated supply chain, and uncertain broad cost advantages remain important limitations. Sodium-ion is becoming a serious second chemistry—not a universal successor.
Frequently Asked Questions
What is CATL’s sodium-ion battery called?
CATL calls its sodium-ion battery product family Naxtra. The company introduced a passenger-EV battery and a 24V integrated start-stop battery for heavy-duty trucks in April 2025.
What are the reported Naxtra specifications?
CATL reports 175 Wh/kg for its passenger-EV cell, more than 10,000 cycles, a 500-kilometer claimed range, and 90% usable power retention at −40°C. These figures are manufacturer claims and have not been independently established by the evidence discussed here.
Will sodium-ion batteries replace lithium-ion?
No. Sodium-ion has potential advantages in cold-weather performance, resource diversification, and selected storage applications, but it generally has lower energy density and a less mature supply chain than lithium-ion. CATL’s own dual-chemistry strategy treats sodium-ion as complementary rather than universally superior.
When will sodium-ion cars be available?
CATL and Changan announced a mass-production passenger vehicle using sodium-ion batteries, with market arrival planned for mid-2026. That announcement does not establish worldwide or U.S. consumer availability.
The Bottom Line
CATL’s Naxtra makes sodium-ion batteries commercially relevant, especially for extreme cold, commercial vehicles, and stationary storage. It does not yet make sodium-ion a universal replacement for lithium-ion.
