CATL's Breakthrough Innovations in Battery Technology

On April 21, 2025, at the inaugural Super Tech Day, CATL made waves in the battery industry by launching three groundbreaking products designed specifically for electric vehicles (EVs). These include the Dual-Power Freevoy battery, the Naxtra battery - the world’s first mass-produced sodium-ion battery, and the second generation of their Shenxing Superfast Charging battery. These innovations are set to redefine existing boundaries, leading the industry into a new multi-energy era.

Introduction of Naxtra and Freevoy Technologies

The Freevoy Dual-Power Battery

The Freevoy Dual-Power Battery features a pioneering dual-power design that integrates a cross-chemical system, overcoming limitations faced by traditional battery technologies. This innovative architecture accommodates the specific requirements of users by incorporating two independent energy zones, thus enabling various functions like dual high/low voltage operations, thermal management, and safety measures. Such a comprehensive system ensures consistent performance and reliability, especially critical for the upcoming autonomous driving era.

Naxtra: A Game Changer for Battery Technology

The Naxtra battery stands out as the first sodium-ion battery to enter mass production. This innovation effectively addresses resource limitations by offering a naturally safe alternative to lithium, thus promoting a shift toward energy independence. With robust reserves making it an ideal candidate for the industry, sodium-ion technology enhances the foundation of new energy technologies.

The Naxtra lineup includes two significant variations: the personal EV battery and the integrated 24V start-stop battery for heavy-duty vehicles. Notably, these batteries can function across extreme temperature ranges from -40°C to +70°C, shattering previous performance limits. The personal EV variant retains 90% of its usable energy even at -40°C, assuring consistent operation in severe cold.

Additionally, the Naxtra battery boasts an impressive energy density of 175 Wh/kg, making it the leader in sodium-ion batteries globally, rivaling lithium iron phosphate (LFP) batteries. The range extends up to 500 kilometers, with a lifespan of over 10,000 cycles, substantially reducing maintenance costs and enhancing safety features to prevent combustion risks.

Enhanced Integrated 24V Start-Stop Battery for Heavy Vehicles

CATL's 24V integrated start-stop battery for heavy trucks ensures a lifespan of over eight years. Compared to conventional lead-acid batteries, it reduces overall lifecycle costs by a remarkable 61%. This battery design allows deep discharge capabilities while facilitating cold starts even in freezing conditions and can resume functionality after a year of inactivity. By offering increased efficiency and reducing environmental impact, CATL firmly positions heavy-duty vehicles toward a lead-free future.

Shenxing Superfast Charging: Setting New Standards

Following the launch of their Shenxing 4C Superfast Charging battery in 2023, CATL has now introduced an upgraded second-generation version that significantly enhances quick-charging capabilities. This LFP battery can traverse distances of up to 800 kilometers with peak charging speeds reaching 12C. It heralds a new phase in charging technology, allowing for a charging rate of 2.5 kilometers per second, virtually eradicating user frustration associated with long wait times.

In low-temperature environments as low as -10°C, the Shenxing Superfast Charging battery can achieve an 80% charge from just 5% in approximately 15 minutes—100% quicker than current industry standards. This ensures performance is consistently maintained across various temperatures, even during low-charge situations, enabling compliance with acceleration requirements.

Pioneering Towards a Multi-Energy Future

What characterizes CATL's multi-energy battery solutions is their transition from 'managed parameter' power batteries to 'demand-driven.' This strategic shift focuses on user requirements, allowing different chemical systems to be integrated flexibly to meet diverse driving scenarios.

CATL is paving the way for a transformative impact across various sectors, not just personal EVs, but also electric buses, heavy-duty trucks, aircraft, and marine vessels. This comprehensive approach aims to accelerate the industrialization of renewable energy and enhances the application of advanced technologies, including semiconductor batteries, in various scenarios.

Throughout these innovations, CATL emphasizes collaboration across different energy systems, overcoming technological barriers, and ensuring that prospects for battery applications expand profoundly. With these groundbreaking products, CATL is truly stepping into the era of multi-energy, catering to future demands and user-centric development in transportation.
