Tencent News's contributing author Guo Yifei interviewed CATL Chairman Zeng Yuqun at CATL’s Super Tech Day. During the interview, Zeng emphasized that CATL is transitioning from a parameter-driven phase to a demand-led approach in power battery development and launched what it claims are the world’s first mass-produced sodium-ion batteries: “Sodium Lion Battery” and "Xunhe Double Core Battery.” These innovative technologies overcome material performance limitations and provide more stable and reliable power for future L3 and L4 autonomous driving applications.
