CATL unveiled the first mass-produced sodium-ion batteries ahead of the Shanghai Auto Show, showcasing their effectiveness in extreme cold conditions. While less energy-dense than lithium-ion batteries, these new batteries have notable advantages such as faster charging and environmental benefits due to sodium's abundance. The brand Naxtra will manufacture these batteries for a variety of vehicles, and CATL claims impressive performance such as maintaining charging speeds at -40 degrees Fahrenheit. Sodium-ion technology may be best suited for compact EVs and hybrids, particularly in colder climates, despite lithium's dominance in the market.
The battery world wasn't bullish about sodium-ion EV batteries until top Chinese battery companies went all in on the tech.
CATL's new brand, Naxtra, aims to produce sodium-ion batteries for various applications, boasting exceptional cold-weather performance and fast charging.
Sodium is 1,000 times more abundant than lithium, making its environmental impact significantly lower despite the lower energy density.
With a range of 124 miles in PHEV and up to 310 miles in pure EV, sodium-ion batteries offer viable options for compact and hybrid vehicles.
