Contemporary Amperex Technology Co., Limited (CATL) has unveiled its latest battery innovations in Shanghai, reinforcing its leading position in the competitive battery industry. Ahead of the Shanghai Auto Show, CATL introduced the Naxtra sodium-ion battery brand, the Shenxing battery line, and the Freevoy dual-power battery during a Tech Day event.
The Naxtra sodium-ion batteries represent a significant advancement in energy density and range. The Naxtra passenger car battery, set for mass production in December 2025, boasts an energy density of 175 Wh/kg, comparable to lithium iron phosphate (LFP) batteries and among the highest globally for sodium-ion technology. This battery maintains 90 percent of its power at temperatures as low as -40°C and supports over 10,000 charge cycles, which helps reduce maintenance costs. Additionally, the Naxtra 24V integrated start-stop battery for heavy-duty trucks will begin mass production in June 2025, offering a service life of more than eight years and a 61 percent reduction in total life cycle costs compared to traditional lead-acid batteries.
CATL also introduced the second-generation Shenxing Superfast Charging Battery, which sets a new benchmark for ultra-fast charging performance. This LFP battery supports an 800-kilometer range and achieves a 12C peak charging rate, enabling a charge from five percent to eighty percent in just fifteen minutes. With a peak charging power of up to 1.3 MW, the Shenxing battery maintains strong output across all temperature ranges and states of charge, even at low-charge levels.
The Freevoy Dual-Power Battery features two independent energy zones, utilizing CATL’s dual-power architecture and self-forming anode technology. This design increases the battery’s volumetric energy density by up to 60 percent and gravimetric energy density by up to 50 percent. The dual-power system ensures continuity, stability, and safety of power output, making it well-suited for the emerging L3 and L4 autonomous driving technologies. CATL announced three dual-power solutions, including a Sodium-LFP Dual-Power Battery that combines Naxtra with an LFP self-forming anode battery, achieving up to 1,000 kilometers of pure electric range in certain sedans. These technologies are also being adapted for use in electric buses, heavy-duty trucks, airplanes, ships, and industrial applications, facilitating the adoption of cutting-edge technologies like solid-state batteries.
With a global EV battery market share of 38.2 percent in the first two months of 2025, CATL remains the only battery supplier worldwide with a market share exceeding 30 percent. This leadership is underscored by the introduction of its new battery technologies, which aim to meet the growing demands of the electric vehicle industry and address increasing competition from rivals such as BYD.
