SMM learned that BAIC R&D recently announced the successful development of sodium-ion battery prototypes. The first prismatic battery pack using prismatic battery cells achieved an energy density exceeding 170 Wh/kg, placing it in the industry’s top tier. It also supports 4C ultra-fast charging, enabling recharging in 11 minutes. Its temperature-range adaptability and safety performance are outstanding, with stable operation across an ultra-wide range from -40°C to 60°C, energy retention above 92% at -20°C, and no risk of thermal runaway under extreme scenarios. At present, this sodium-ion battery has completed sample finalization, established mass-production processes for prismatic products, and filed 20 patents around core technologies. BAIC has also leveraged this to complete a full technology roadmap covering lithium batteries, solid-state batteries, and sodium-ion batteries, and has mastered a complete set of core sodium-ion battery technologies.
