CATL reveals new EV batteries with super-fast charging

CATL has just revealed exciting new developments in the EV battery space that promise to make owning and using electric vehicles even easier and more convenient for everyone.

One of the biggest announcements is CATL's next-generation Shenxing battery, designed specifically for super-fast charging. According to the company, you can add 323 miles of driving range to your EV in just five minutes. That works out at about 1.6 miles of range added every single second you're plugged in. This kind of speed could make charging stops as quick as filling up a gas tank, which is a huge step forward for people considering making the switch to electric cars.

The company says these new batteries can achieve a total range of up to 497 miles on a full charge. What's even better is that they can charge from a low 5% to 80% in just 15 minutes, even when the temperature drops to a chilly 14°F.

CATL also unveiled a new battery system called "Freevoy Dual Power Battery." This clever tech combines two different battery packs into one. By doing this, an EV could potentially travel over 932 miles on a single charge - apparently. This system uses two separate battery sections with different materials inside.

One section acts as the main power source, and the other kicks in when the main battery runs low, similar to a backup fuel tank. While this second battery charges slower and won't be used as often, it offers a significant boost in overall driving distance. CATL believes this technology could be in production EVs within the next two to three years, although they haven't said which carmaker will be the first to use it.

Finally, CATL is also making huge progress with sodium-ion batteries. These batteries are expected to start being produced in December 2025. Sodium-ion batteries could be a good alternative to the lithium-ion batteries commonly used in EVs today. One big advantage is how well they perform in cold weather, which could be great news for people living in colder climates. CATL has even tested these batteries in extreme conditions, showing they are very safe and don't easily catch fire.

The sodium-ion batteries can also store a good amount of energy, offering over 124 miles of range in plug-in hybrid EVs, and can last for a long time, with the ability to be charged 10,000 times. Even in freezing temperatures as low as -22°F, they can charge from 30% to 80% in just 30 minutes and will still work normally even at -40°F. As the technology gets more advanced, sodium-ion batteries are expected to be cheaper to make than traditional lithium-ion batteries, which could eventually lead to lower prices for electric cars.
