China’s leading battery manufacturers are accelerating the development of solid-state battery technology, a key innovation expected to transform sectors ranging from electric vehicles (EVs) to flying cars and robotics. The shift promises greater energy density, enhanced safety, and reduced manufacturing costs compared to traditional lithium-ion batteries.
In early May, Gotion High-Tech initiated road tests for its next-generation all-solid-state batteries, following the successful completion of China’s first fully localized 0.2 gigawatt-hour pilot production line. The company also unveiled its G-Yuan battery, which delivers an energy density of 300 watt-hours per kilogram. According to Gotion’s chief scientist Zhu Xingbao, the battery is designed for use in electric vertical takeoff and landing (eVTOL) aircraft, EVs, and humanoid robots.
Meanwhile, Ganfeng Lithium announced that it has established a comprehensive solid-state battery ecosystem, covering research, development, and production. The company currently offers products with an energy density of 420 Wh/kg and has developed prototypes achieving 500 Wh/kg.
Contemporary Amperex Technology Co. Ltd. (CATL), the world’s largest EV battery maker, revealed in mid-May that its solid-state batteries can also reach 500 Wh/kg. CATL is applying this cutting-edge technology in a civilian electric passenger aircraft project, ensuring compliance with stringent aviation safety and quality standards through ongoing testing.
These advancements place China at the forefront of solid-state battery innovation, setting the stage for breakthroughs in next-generation transportation and intelligent robotics.
