- CATL’s second-gen Shenxing batteries can add 1.6 miles of range per second of charging.
- Dual-power batteries promise over 930 miles of driving range for electric vehicles.
- Sodium-ion batteries are safer, more resilient to cold weather, and could be cheaper.
Electric vehicles are evolving rapidly, and if you’re still skeptical, CATL has just unveiled a series of significant advancements in battery technology that will soon make their way into production models. The highlights include next-generation Shenxing batteries with ultra-fast charging capabilities, a new dual-power battery system for EVs, and sodium-ion batteries designed to perform better in colder climates.
Fast-Charging: A Game-Changer for EVs
The fast-charging news are probably the most important for the future of EVs, as they will eventually make charging stops as quick and easy as refueling stops for ICE-powered vehicles. In this context, CATL promises that its second-gen Shenxing batteries will add 520 km (320 miles) of range in five minutes of charging, which is the equivalent of gaining 2.5 km (1.6 miles) of range per second.
The fast-charging technology is undoubtedly the most significant development for the future of EVs, bringing us closer to a world where charging an electric vehicle is as quick and convenient as refueling a gasoline car. CATL’s second-gen Shenxing batteries aim to achieve just that, with a claimed ability to add 520 km (320 miles) of range in just five minutes of charging. To put that into perspective, that’s 2.5 km (1.6 miles) of range per second or about as fast as it takes to fill your average American car with gas.

The impressive figure surpasses earlier developments by rival BYD, whose batteries will be able to add 400 km (249 miles) of range in just five minutes. For comparison, the first generation of CATL’s Shenxing batteries, which debuted in 2023, could replenish 400 km (249 miles) of range in ten minutes.
More Range, More Charging Speed, Even in the Cold
CATL’s second-gen Shenxing batteries promise a total range of up to 800 km (497 miles). Even better, they’ll be able to charge from 5% to 80% in just 15 minutes, even at chilly temperatures as low as -10°C (14°F). While we don’t yet know how many of the 67 new EVs launching in 2025 will be equipped with these second-gen batteries, it’s safe to say that the technology is coming sooner rather than later.
Dual-Power Batteries for Seriously Long Range
Another interesting development from CATL is the “Freevoy Dual Power Battery” technology. By combining two battery packs into one, an electric vehicle could achieve a range of over 1,500 km (932 miles), putting it on par with the most efficient range-extender hybrids. The new design splits the battery pack into two independent energy zones with different cell materials, somewhat akin to the dual-engine systems used in aircraft.
The auxiliary battery, acting as a range extender, won’t use graphite, making it smaller and cheaper to produce. However, the trade-off is slower charging speeds and fewer charging cycles, as these auxiliary batteries will only come into play once the main battery is empty, so they won’t be charged nearly as often.
CATL expects this dual-power battery technology to reach production EVs in the next 2-3 years, though they’re staying tight-lipped about which automaker will be the first to adopt it.
Sodium-Ion Batteries: Cold-Weather Warriors
Last but not least, CATL is advancing sodium-ion batteries, which are set to enter production in December 2025. These could potentially replace the lead-acid batteries in many ICE vehicles, as well as the lithium iron phosphate batteries used in hybrids and EVs. The key advantage of these batteries is their superior performance in cold weather, making them an attractive option for those in frigid climates.
The company claims its tests have shown that sodium-ion batteries can withstand extreme conditions whether it’s being punctured by needles, drilled, or even sliced in half with a power saw, without catching fire or exploding. Safety isn’t the only benefit, though.

These batteries also offer high energy density, providing over 200 km (124 miles) of range in plug-in hybrids (PHEVs) and a robust lifecycle of 10,000 charges. Even at temperatures as low as -30°C (-22°F), these batteries can charge from 30% to 80% in just 30 minutes and will continue to perform normally at -40°C (-40°F).
Additionally, sodium-ion chemistry is expected to be more cost-effective than traditional lithium-ion batteries as the technology matures, which could bring a significant price advantage in the long run.
