Changan’s Golden Bell: A Solid-State Battery Revolution on the Horizon
The promise of solid-state battery technology is edging closer to reality. Chinese automotive giant Changan, parent company of Deepal, is set to integrate its first solid-state batteries into both vehicles and robots this year, marking a significant milestone for the industry.
Unprecedented Range and Energy Density
Changan’s “Golden Bell” batteries boast a record energy density of 400 Wh/kg, rivaling figures recently announced by companies like Donut Lab. This breakthrough translates to an anticipated driving range exceeding 1,500 kilometers (approximately 932 miles) on a single charge – measured using the Chinese CLTC cycle – potentially eliminating range anxiety for long-distance travel.
Safety and Intelligence: Beyond Just Distance
The advancements aren’t limited to range. Changan claims its recent batteries will be approximately 70% safer than conventional batteries, incorporating remote diagnostics powered by artificial intelligence. This proactive safety approach aims to identify and address potential issues before they escalate.
A Phased Approach to Solid-State Adoption
Even as mass production isn’t slated until 2027, Changan is strategically preparing for a gradual transition. The company plans to utilize a portfolio encompassing solid, semi-solid and liquid battery technologies. Initial installations of the Golden Bell batteries will occur in robots and electric vehicles during the third quarter of 2026.
Launched in November 2023, the Golden Bell brand encompasses eight cell variants, with a planned production capacity of 150 GWh. This demonstrates Changan’s commitment to becoming a major player in the battery technology space.
Collaboration with CATL: Exploring Sodium-Ion Alternatives
Changan isn’t solely focused on solid-state technology. The company is also collaborating with CATL on sodium-ion battery development, exemplified by the Naxtra battery pack. This pack offers a density of 175 Wh/kg, operational capability at temperatures as low as -50°C, and a range exceeding 400 kilometers (approximately 248 miles). The Changan Nevo Q05 and Nevo A06 models will be the first to feature this technology, diversifying the brand’s energy solutions.
The Global Race for Solid-State Supremacy
Changan isn’t alone in pursuing solid-state battery technology. Dongfeng Motor is also testing its own solid-state batteries, achieving 350 Wh/kg and over 1,000 km of range, with plans for commercialization before the end of 2026. Major players worldwide – including BYD, Chery, CATL, Mercedes-Benz, Volkswagen, and Toyota – are aligning their efforts to build solid-state batteries a reality.
