CATL Unveils Second-Generation Sodium-Ion Battery with Ultra-Fast Charging.
Contemporary Amperex Technology Co. Ltd. (CATL), the world’s largest electric vehicle (EV) battery manufacturer, has announced its second-generation sodium-ion battery, marking a significant advancement in battery technology. This new battery boasts an energy density exceeding 200 Wh/kg, a notable improvement over the 160 Wh/kg of its predecessor, bringing it closer to the performance of mainstream lithium iron phosphate (LFP) batteries .Batteries News+5Autocar Professional+5Autocar Professional+5Reuters+2SNEC PV++2Batteries News+2
One of the standout features of this second-generation battery is its ultra-fast charging capability. CATL claims the battery can achieve an 80% charge in just 15 minutes at room temperature. Moreover, it maintains efficient discharge performance even in extremely low temperatures, functioning effectively at -40°C, which addresses a common limitation of traditional lithium-ion batteries .Batteries NewsBatteries News+2arenaev.com+2SNEC PV++2
In addition to the sodium-ion battery, CATL has also introduced the second generation of its Shenxing fast-charging EV battery. This battery can deliver a 520 km driving range from a five-minute charge and reach 80% charge in 15 minutes, even in cold weather conditions . Over 67 EV models are set to incorporate the Shenxing battery this year, highlighting CATL’s commitment to advancing EV technology.Electrek+4Reuters+4Financial Times+4
The introduction of sodium-ion batteries presents several advantages over traditional lithium-ion counterparts. Sodium is more abundant and cost-effective than lithium, reducing material costs and supply chain dependencies. Additionally, sodium-ion batteries exhibit lower fire risks, enhancing safety in EV applications .Reuters
CATL’s advancements in battery technology, including the development of the Naxtra sodium-ion battery brand, underscore the company’s dedication to diversifying energy storage solutions. With mass production of the Naxtra battery scheduled to begin in December 2025, CATL aims to provide safer, more cost-effective, and efficient energy storage options for the growing EV market .Business Insider+3Reuters+3Financial Times+3
These innovations by CATL signify a pivotal step toward overcoming existing challenges in the EV industry, such as range anxiety and charging times, thereby accelerating the global transition to sustainable transportation.
