On February 24, Changan Automobile provided updates on its solid-state battery development through the Shenzhen Stock Exchange's interactive platform, confirming that trial installations in vehicles will begin before the third quarter of 2026. This effort is spearheaded by the company's Golden Bell battery system, which has an energy density of 400 Wh/kg and enables a driving range exceeding 1,500 km on a single charge. The technology also features enhanced safety, including a 70% improvement driven by artificial intelligence-enabled remote diagnostics.
The Golden Bell, or Jinzhongzhao, solid-state battery is set for integration into both robots and electric vehicles by the third quarter of 2026, with mass production and wider installations planned for the following year. Launched in November 2023 as an independent brand under Changan, Golden Bell includes eight cell variants spanning liquid, semi-solid, and full solid-state designs, supported by a targeted annual production capacity of 150 GWh.
In addition, Changan is collaborating with CATL on sodium-ion battery technology. Their joint Naxtra pack delivers 175 Wh/kg energy density, performs effectively at temperatures as low as -50°C, and provides more than 400 km of range. The first vehicles to incorporate this technology will be the Changan Nevo Q05 and Nevo A06 models, which were recently showcased at a conference in Yakeshi, China.
