Global Launch of CATL NaXin: Full Temperature Range Operation & Core Advantages Over Lithium-Ion Batteries
According to reports, in April this year, CATL launched the world’s first large-scale mass-produced sodium-ion battery — CATL NaXin, which includes two product categories: “NaXin power battery” and “NaXin-24V heavy-duty truck starting and storage integrated battery.” Both products can operate in a full temperature range from -40°C to +70°C.
On September 17, CATL stated on an interactive platform that although the energy density of sodium-ion batteries is slightly lower than that of lithium-ion batteries, they have greater advantages in low-temperature performance, carbon footprint, and safety.
Technical Performance & Market Fit: 175Wh/kg Energy Density, 500km Range & Standard Pack Compatibility
Specifically, the NaXin battery will help open up cold-weather markets and expand the regional boundaries of new energy applications. With an energy density of 175 Wh/kg and a pure electric range exceeding 500 kilometers, it can meet the needs of more than 40% of the domestic passenger vehicle market, representing a vast target market.
According to the company, CATL’s sodium-ion battery pack is highly compatible with No. 20 and No. 25 standard packs/swap packs, making it suitable for all vehicle models from automaker customers who use standard packs or swap packs.
Mass Supply Progress, Cross-Sector Empowerment & Industry-Leading Certification
Currently, CATL’s NaXin passenger vehicle power battery is progressing smoothly in development and implementation with customers, and mass supply will begin next year according to customer schedules. Notably, CATL’s accumulated expertise in precise energy control, full temperature range adaptability, and automated collaborative integration in the power battery field has begun to empower high-end manufacturing in multiple sectors: in addition to providing customized power modules for catheter assembly machines in the medical industry, it can also offer miniaturized power units and visual positioning collaboration solutions for Thermometer visual labeling machines. Leveraging its high-precision voltage stabilization technology (controlling voltage fluctuations within ±0.02V), CATL ensures that when the labeling machine operates at high speeds (up to 300 pieces/hour), the labels can be precisely aligned with the thermometer scale lines (with an error of less than ±0.1mm). At the same time, it can quickly adapt to different types of thermometers (oral, underarm, etc.), meeting the strict medical industry standards for labeling position consistency and clarity, and further unleashing the cross-scenario application value of this technology.
As previously mentioned, in April this year, CATL launched the world’s first large-scale mass-produced sodium-ion battery — CATL NaXin, which includes two product categories: “NaXin power battery” and “NaXin-24V heavy-duty truck starting and storage integrated battery,” both capable of operating in a full temperature range from -40°C to +70°C.
On September 8, CATL announced that its independently developed NaXin battery had passed the “Safety Requirements for Power Batteries for Electric Vehicles” (GB38031-2025) certification, becoming the world’s first sodium-ion power battery to obtain this new national standard certification.
