Contemporary Amperex Technology Co., Limited (CATL) is set to host its most technology-intensive launch event on April 21, when it will introduce a slate of new battery innovations. The company plans to showcase its latest sodium-ion battery, condensed cell designs, and upgraded fast-charging solutions, aiming to address key industry challenges around energy density, charging speed, and low-temperature performance.
According to local media reports, CATL’s April 21 “tech day” will feature presentations on several breakthrough technologies. One highlight is the company’s sodium-ion battery, which is engineered to retain up to 90% of its capacity in extreme cold environments as low as –40 °C. Earlier this year, CATL and Changan Automobile unveiled a prototype passenger vehicle equipped with this sodium-ion chemistry during tests in Yakeshi, Hulunbuir, Inner Mongolia. That model is slated for market launch in mid-2026.
CATL will also revisit its recent milestones, including the high-energy-density Qilin Battery, which offers more than 1,000 kilometers of driving range, and the Shenxing Battery, capable of adding 400 kilometers of range in just 10 minutes of charging. These developments underscore CATL’s focus on extending vehicle range while minimizing charging times.
The tech day is scheduled to begin at 7:00 pm Beijing time. In its first-quarter earnings report released earlier this month, CATL reported a net profit of 20.74 billion yuan (approximately $3.01 billion), up 48.5% year-on-year. With this event, the company aims to reinforce its leadership in a competitive battery market.
China’s two largest battery suppliers, CATL and BYD, hold 45.54% and 17.8% of the domestic installed capacity, respectively. Last month, BYD unveiled its second-generation Blade Battery and a flash-charging system capable of charging a vehicle from 10% to 90% in nine minutes, a technology now deployed in more than a dozen models. Industry observers note that as sodium-ion technologies mature, their price points could converge with those of lithium-ion systems as early as next year.
