Ganfeng Lithium has begun small-scale production of solid-state batteries that achieve an energy density of 500 watt-hours per kilogram (Wh/kg), according to details released in minutes from a recent investor relations meeting. This marks the first time a 10 ampere-hour solid-state battery has reached the 500 Wh/kg threshold, establishing a new industry benchmark for lithium-metal battery commercialization.
In parallel with this ultra-high-density offering, Ganfeng reported progress in testing a 400 Wh/kg solid-state cell. Engineers have validated its performance through more than 1,100 charge-discharge cycles, demonstrating robust cycle life and readiness for scale-up.
Within its solid-state battery program, Ganfeng is pursuing two anode technologies: silicon-carbon and lithium-metal. The company is emphasizing lithium-metal anodes to accelerate mass production of batteries with high specific energy. In 2025, research and development expenses represented 4.51 percent of Ganfeng’s total operating revenue, reflecting the company’s commitment to innovation.
Next-generation solid-state batteries from Ganfeng are aimed at high-end electric vehicles, urban air mobility, robotics, and consumer electronics. Early adoption includes integration of the company’s high-density cells in the AE200-100 electric vertical takeoff and landing (eVTOL) aircraft developed by Aerofugia Technology, a unit of Geely.
Looking ahead, Ganfeng expects global lithium supply and demand to remain tightly balanced through 2026 and 2027. The company noted that recent years of weak lithium prices have suppressed large-scale capital investment across the industry, which could limit new supply growth in the near term.
By advancing solid-state battery designs and scaling production capacity, Ganfeng aims to position itself at the forefront of next-generation energy storage solutions for multiple high-growth markets.
