The world’s largest EV battery maker, CATL, has just launched a new brand called Naxtra, focused on sodium-ion batteries. These batteries are set to hit the market in December 2025. CATL was the first company globally to introduce sodium-ion batteries back in 2021. Sodium is different from other materials because it’s easy to extract from cheap table salt and is more readily available than the lithium used in most EV batteries. Plus, it reduces the risk of fires. Alongside Naxtra, CATL also unveiled their second-generation fast-charging battery.
Naxtra’s First Product
The Naxtra brand is kicking off with a new sodium-ion battery that packs 175 watt-hours per kilogram. This energy density is almost on par with lithium iron phosphate (LFP) batteries, which are commonly used in EVs and energy storage systems. LFP batteries typically have an energy density of 150-180 watt-hours per kilogram. CATL believes sodium-ion batteries could replace up to half of their LFP battery market share due to their lower production costs.
Sodium-ion batteries offer several advantages. They’re not only cheaper but also safer, with a lower risk of catching fire. They perform well in cold temperatures, down to -40°C. The extraction process is more environmentally friendly than mining lithium or cobalt. They also reduce battery degradation issues and can support a driving range of up to 500 kilometers. Since they can work with existing infrastructure without needing major changes, they’re a good fit for budget-friendly EVs that don’t need super-long ranges. This is particularly appealing given the intense price competition in the EV market.
CATL’s Other Innovations
CATL has also introduced Shenxing V2, their second-generation fast-charging battery. It can provide a 520-kilometer range with just five minutes of charging. In cold weather, it can charge from 0% to 80% in 15 minutes. Over 67 new EV models launching this year will be powered by Shenxing batteries.
Another innovation is the CATL Freevoy Dual Power Battery. This battery features a dual-core design, with a main power zone and an extended range zone. It can support a driving range of over 1,500 kilometers on a single charge, making it competitive with hybrid vehicles. The battery also includes a pairing system similar to twin-engine jets, enhancing safety by allowing one pack to take over if the other fails. This system can also isolate overheating battery packs.
CATL’s Global Presence
CATL’s batteries are already installed in over 18.32 million EVs operating in more than 66 countries worldwide. In 2024, the company reported a 15% increase in net profit compared to the previous year. While this growth is notable, it’s the slowest in six years, largely due to the intense price competition in China’s EV market.
