Technological breakthroughs and accelerated industrialization

The milestone significance of CATL's Naxin-brand sodium-ion battery

On April 21, 2025, during its “Super Tech Day,” CATL officially launched its sodium-ion battery brand Naxin-brand sodium-ion battery,” marking a major breakthrough in sodium battery technology and the beginning of large-scale application.

  • Performance Leap: The Naxin passenger vehicle battery achieved an energy density of 175Wh/kg—the highest among mass-produced sodium batteries globally—comparable to lithium iron phosphate (LFP) batteries, enabling a pure electric range of 500 km (200 km for hybrid vehicles).
  • All-Temperature Adaptability: Naxin-brand sodium-ion batteries can operate stably in extreme temperatures from -40°C to 70°C. Even at -40°C, they retain 90% usable capacity, solving cold-climate range degradation issues.
  • Ultra-Long Lifespan and Fast Charging: The Naxin-brand sodium-ion battery offers over 10,000 cycle life (explore lithium ion battery life cycle) and supports peak 5C charging (30%-80% recharge in just 10 minutes), significantly reducing maintenance costs.
  • Safety Innovations: Utilizing cobalt- and nickel-free materials and optimized structures, the batteries eliminate thermal runaway risks. They remained fire- and explosion-free under extreme tests such as puncture, compression, and drilling, achieving intrinsic safety.

Global acceleration of sodium battery industrialization

Beyond CATL, many enterprises and research institutions worldwide are actively promoting the industrialization of sodium batteries:

  • China: Funeng Technology’s sodium-ion batteries have been installed in JMC models and delivered. Huayu Sodium Energy projects BOM costs for sodium cells could drop to ¥0.20/Wh within 2-3 years. China has prioritized sodium batteries in its new energy storage technologies, rapidly improving the entire industry chain.
  • Europe: Companies like Northvolt and Tiamat Energy hold advantages in sodium battery research and material innovation, pushing for storage sector applications.
  • North America: Natron Energy and Altris AB are active in the commercialization and market expansion of sodium batteries, focusing on energy storage and specialized applications.

Diversified application scenarios and market potential

Electric vehicle market: Differentiated competition strategy

With advantages in cost and low-temperature performance, sodium batteries will create differentiated competition with lithium batteries in the EV sector.

  • A0 to B-Class Vehicles: The Naxin power battery is suitable for A0 to B-class vehicles, targeting high cost-performance and excellent cold-resistance. Mass production is expected by December 2025, first installed on Chocolate battery swap models.
  • Commercial Vehicles: The Naxin 24V integrated heavy truck starter battery will replace traditional lead-acid batteries (explore lead acid motorcycle battery), offering an 8-year lifespan and 61% lower lifecycle costs. It supports -40°C one-click starting and will be mass-produced in June 2025 in partnership with FAW Jiefang.
Diverse application scenarios unlock the full potential of sodium batteries

Two-Wheel electric vehicles: Performance and cost advantages

Sodium batteries have broad application prospects in two-wheelers. Equipped with Naxin batteries, electric two-wheelers become lighter, offer longer range, maintain winter performance, and enhance safety—potentially achieving “one bike, one battery,” thus reducing user costs.

Energy storage: Ideal for large-scale applications

Sodium batteries, with abundant resources, low cost, and high safety, are ideal for large-scale storage applications such as grid balancing, renewable energy integration, and industrial/commercial storage.

Other application scenarios: Continuous expansion

Sodium batteries can also be applied in automotive start-stop systems, backup power supplies, and electric tools, with potential for even broader future applications.

Resource security and cost advantages: Key drivers

Lithium resource bottlenecks and strategic value of sodium batteries

Recent rises in lithium raw material prices have raised concerns over supply chain security. The Democratic Republic of Congo’s suspension of cobalt exports has exacerbated cobalt supply tension, driving up nickel prices and, consequently, ternary lithium battery costs. Meanwhile, the popularity of high-voltage LFP materials has further increased LFP battery costs.

Sodium batteries require no cobalt or nickel and benefit from the abundant sodium resource (420 times the crustal abundance of lithium), freeing them from reliance on scarce metals and lowering raw material costs, thus addressing potential “resource chokepoints.”

Cost leadership drives rapid market adoption of sodium batteries

Cost advantages accelerate market penetration

As the sodium battery supply chain matures and mass production scales up, costs will continue to decline. Huayu Sodium Energy forecasts that within 2-3 years, BOM costs for sodium battery cells could drop to ¥0.20/Wh, highlighting the cost advantage and creating room for capturing mid- to low-end markets.

CATL reports that material costs for sodium batteries are about 30% lower than those for lithium batteries, while green, recyclable production processes emit 60% less carbon and achieve a recycling rate of over 99%, supporting a low-carbon lifecycle.

Sodium vs. lithium: A diversified, win-win future

Industry consensus suggests that no single battery type will dominate all scenarios in the next five years; sodium and lithium batteries will complement each other in different fields.

Sodium batteries will coexist with LFP and ternary lithium batteries, mitigating lithium supply risks and offering low-cost solutions for storage and two-wheeled vehicles.

It is predicted that sodium batteries may replace 30%-40% of the current LFP market share and achieve several hundred GWh of installed capacity by 2035.

Global sodium battery market outlook: A promising future

Sodium and lithium batteries A complementary force for global energy transition and sustainability

Despite current challenges, the global sodium battery market holds immense promise. With continuous technological breakthroughs, falling costs, and expanding application scenarios, sodium batteries will play an increasingly vital role in global energy transition efforts.

  • Global Installed Capacity Forecast: CATL projects that global sodium battery installed capacity will exceed 150GWh by 2027 (explore the top 10 lifepo4 battery installed capacity manufacturers), accelerating “de-lithiation” progress.
  • Billion-Dollar Market Scale: Driven by global energy transition demands, institutions predict that sodium batteries will form a billion-dollar market by 2030.
