CATL Launches Naxtra Battery and Dual-Power Technologies

On April 21, 2025, during its inaugural 'Super Tech Day', CATL (Contemporary Amperex Technology Co., Limited) introduced three innovative battery systems that are set to redefine the landscape of electric vehicle (EV) power solutions. Among them is the Naxtra battery, known as the world's first mass-produced sodium-ion battery, which promises to enhance the scale and efficiency of future energy systems, moving beyond traditional lithium-ion technologies.

Breakthrough Technologies in Battery Innovation

CATL's offerings include the Freevoy Dual-Power battery, the Naxtra sodium-ion battery, and the second generation of the Shenxing battery known for its ultra-fast charging capabilities. The Freevoy Dual-Power battery stands out with a dual energy architecture that allows simultaneous functioning of two independent energy zones, optimizing energy performance across varying conditions.

The Naxtra battery utilizes sodium, a more abundant and accessible resource, significantly reducing reliance on lithium, and aiming to provide a more stable and sustainable source for battery production. With an impressive energy density of 175 Wh/kg and ability to function efficiently in extreme temperatures, this technology marks a significant step forward in mitigating material cost barriers for manufacturers.

Notably, despite severe cold temperatures dropping to -40 °C, the Naxtra battery retains 90% operational capacity and can sustain performance even in low charge states, with 10% charge remaining. This feature eliminates concerns over performance degradation in harsh conditions, making it ideal for various climates.

Dual-Power Architecture Provides Flexibility

The Freevoy Dual-Power battery integrates cutting-edge technologies including a self-forming anode and two distinct performance zones. This architecture allows the battery to adapt to driver behavior and environmental conditions seamlessly, enhancing range and efficiency. CATL’s approach not only empowers consumers with better energy solutions but also supports automotive manufacturers in adopting advanced, adaptable energy systems as they move toward introducing next-generation vehicles with autonomous driving capabilities.

The introduction of various chemistries within the Freevoy framework, including combinations of sodium-ion, lithium iron phosphate (LFP), and nickel cobalt manganese (NCM) technologies, illustrates a commitment to maximizing versatility in energy storage solutions. By intelligently managing energy allocation depending on driving patterns, CATL’s batteries are set to redefine consumer expectations of performance, safety, and efficiency.

The Shenxing Battery: Setting Racing Records

Another highlight from CATL's Super Tech Day was the second generation of the Shenxing super fast-charging battery. This groundbreaking product achieves charging speeds of up to 12C and can deliver up to 800 km of driving distance on a single charge. Shenxing's impressive capability to charge to 80% in just 15 minutes, even at low temperatures, addresses long-standing frustrations associated with EV charging times.

This technological leap represents more than just battery efficiency; it showcases CATL’s relentless pursuit of excellence and user-oriented design. The batteries are engineered to sustain high performance across varied conditions and perfectly align with the automobile industry's shifting demand for quick and reliable energy solutions.

Future Implications of CATL's Innovations

As CATL pioneers these revolutionary technologies, the implications extend beyond just personal vehicles. The innovations introduced are expected to influence various sectors, including public transit, commercial fleets, aviation, marine applications, and industrial operations — paving the way for expansive industrialization of renewable energy across global markets.

CATL's foresight in creating adaptable battery technologies aligns with broader sustainability goals, working to ensure that as the world transitions to electric mobility, solutions remain robust, efficient, and eco-friendly. The dawn of the multi-source energy era symbolizes CATL's commitment to reshaping the energy landscape and establishing safer, more sustainable future power solutions for both consumers and industries alike.

In conclusion, as CATL continues to explore and push the limits of energy storage technology, it is clear that these advancements will play a significant role in redefining how we approach energy utilization in our day-to-day lives and across various industries. With the capabilities of the Naxtra battery and the innovative dual-power architecture, CATL lays the groundwork for a future rich with possibilities for electric mobility and renewable energy integration.
