| CATL sodium-ion battery teaser. |
In a strategic pivot that could reshape the cost and availability of energy storage, Contemporary Amperex Technology Co., Limited (CATL), the world’s largest battery manufacturer, has announced it will begin mass production of its advanced sodium-ion batteries in 2026. The move capitalizes on shifting raw material economics and promises to bring its record-breaking Naxtra line to electric vehicles, grid storage, and beyond.
From Backburner to Front Line: The Lithium Price Catalyst
The journey to this decision highlights the volatile dance of commodity markets. CATL had already developed a formidable sodium-ion (Na-ion) cell technology years ago, achieving energy densities that rival mainstream lithium iron phosphate (LFP) batteries. However, the plans were deprioritized after a steep fall in lithium carbonate prices from their 2022 peak.
The recent recovery of lithium, driven in part by regulatory actions in China that constrained mine output, has changed the calculus. As reported by iTHome, the shift in the market dynamics has been significant, with the end of the bear market prompting a reassessment of alternative chemistries.

With lithium prices firming, the inherent cost advantage of sodium—a far more abundant and geographically widespread material—has come roaring back. CATL confirms that Na-ion cells are now cheaper to produce than standard LFP batteries, leading to a wave of client interest. "Clients have started notifying CATL that they are now ready to take delivery," a company insider noted.
Naxtra: Not a Substitute, But a Star Performer
CATL is positioning its Naxtra line not merely as a cheaper alternative, but as a superior solution for specific conditions. Its flagship achievement is a mass-producible cell with an energy density of 175 Wh/kg, putting it nearly on par with the LFP packs found in millions of EVs and storage units today.
But the real selling point is performance where lithium struggles. The Naxtra battery boasts an operational temperature range of -40°C to 70°C and has become the world's first commercial-grade sodium-ion battery to pass China's rigorous new safety standards.
"An electric car equipped with our sodium-ion battery will be able to cover more than 300 miles on a charge, even in extreme cold," stated a CATL representative. This claim will be put to the test in 2026 when the first mass-produced Naxtra packs are delivered to a host of undisclosed clients.
The cold-weather resilience is a key advantage. Sodium-ion batteries do not suffer the same drastic capacity loss in freezing temperatures as lithium-ion counterparts. This technology is already trickling down to consumers; for instance, 12V sodium starter batteries that maintain capacity in the cold are now available for purchase on platforms like Amazon.
A Dual-Chemistry Future
CATL envisions a future where sodium and lithium batteries "shine brightly" together. The deployment strategy for Naxtra is expansive:
- Electric Cars: Primarily for entry-level and mid-range models, offering a cheaper, cold-weather-resilient option.
- Energy Storage Systems (ESS): Ideal for large-scale grid storage where cost, safety, and longevity are paramount.
- Commercial Vehicles & Battery Swap Stations: Where fast charging, cycle life, and operational stability in varied climates are critical.
By bringing Naxtra to mass production, CATL isn't just launching a new product—it's diversifying the global energy ecosystem. This move could reduce the automotive and storage industries' dependency on lithium, mitigate supply chain risks, and ultimately accelerate the adoption of electrification by offering a powerful, cost-effective, and robust battery solution for the real world. All eyes will be on 2026 as the first wave of these next-generation batteries hits the market.
