Xibei Power releases 25Ah sodium-ion battery, achieving 230Wh/kg energy density

Beijing Xibei Power Technology Co., Ltd. (referred to as: Xibei Power) successfully developed a 25Ah sodium-ion battery in November 2024, achieving a weight energy density of 230Wh/kg. The battery uses negative-electrode sodium-ion battery technology to form an "actual negative electrode" through in-situ electrochemical deposition during the first charging process, thereby significantly increasing the energy density of the full battery.
