CATL’s Naxtra Sodium-Ion Battery Set to Disrupt EV Industry
Table of Contents
August 17, 2025 - Contemporary Amperex Technology Co. Limited (CATL), the world’s leading battery manufacturer [[1]], is poised to introduce a groundbreaking sodium-ion battery, dubbed Naxtra, that could significantly lower the cost of electric vehicles and extend battery lifespan. Production is ramping up,with initial deliveries to six automakers slated for 2026.
A Leap in Battery Technology
The Naxtra battery represents a strategic shift away from reliance on lithium, nickel, manganese, and cobalt – materials often subject to price volatility and geopolitical concerns.Rather,it utilizes sodium,an abundant and inexpensive element commonly found in salt. This innovative approach is projected to reduce battery production costs to approximately 10% of current lithium-ion battery prices.
CATL initially unveiled plans for the sodium-ion battery in April 2025 alongside other advancements, but is now moving swiftly toward large-scale production. this commitment underscores the company’s confidence in the technology’s potential to reshape the energy storage landscape.
How Naxtra Differs from Existing Batteries
While sodium-ion batteries have been explored for years, previous iterations suffered from lower energy density and increased weight, limiting their suitability for automotive applications. CATL’s Naxtra battery overcomes these limitations with an electrolyte designed to prevent dendrite formation and degradation, ensuring stable performance across a wide temperature range.
the battery operates effectively between -40°C and +70°C, maintaining 90% of its discharge power even at -40°C. This resilience is a notable advantage over customary lithium-ion batteries, which can experience performance drops in extreme temperatures.
Key Specifications of the Naxtra Battery
| Feature | Specification |
|---|---|
| Energy Density | 175 Wh/kg (cell level) |
| Estimated Range | 500 km (real-world driving) |
| Cycle Life | 10,000+ cycles |
| Operating Temperature | -40°C to +70°C |
| Projected cost | 10% of Lithium-ion |
Did You Know? Sodium-ion batteries eliminate the risk of thermal runaway, a common safety concern with lithium-ion batteries, as they lack components that support combustion.
Building on LFP Technology
CATL’s development of the Naxtra battery builds upon its success with Lithium Iron Phosphate (LFP) batteries, which already offer a cost-effective alternative to traditional lithium-ion chemistries. LFP batteries currently represent 40-70% of the cost of comparable lithium-ion batteries, providing a 30-60% cost reduction. [[3]] The Naxtra battery promises to further reduce costs,potentially making EVs more accessible to a wider range of consumers.
Northvolt, a European battery manufacturer, previously announced a solid-state sodium-ion battery with a comparable energy density in 2023, but faced challenges in scaling production. CATL’s approach, utilizing a more conventional electrolyte, appears to be accelerating the path to commercialization.
Pro Tip: The extended cycle life of the Naxtra battery – exceeding 10,000 cycles – translates to a potential lifespan of 5 million kilometers, offering exceptional long-term value.
Impact on the EV Market
The introduction of the Naxtra battery is expected to intensify competition within the electric vehicle market. With a projected cost reduction of up to 80-90% compared to lithium-ion batteries, automakers utilizing Naxtra technology could offer EVs at significantly lower price points – potentially reducing costs by 7,000 to 10,000 euros per vehicle.
This cost advantage could force other battery manufacturers and automakers to adopt similar technologies or risk losing market share. Will this shift lead to a more affordable and enduring future for electric mobility? What innovations will emerge as competitors respond to CATL’s breakthrough?
The development of sodium-ion batteries represents a crucial step towards diversifying battery chemistries and reducing reliance on critical materials. This trend aligns with broader sustainability goals and efforts to build a more resilient supply chain for the EV industry.Ongoing research focuses on further improving energy density and cycle life of sodium-ion batteries, paving the way for even more advanced energy storage solutions in the future.
