Chinese battery producer Gotion High-tech has entered into a strategic cooperation with German chemical firm BASF to advance solid-state battery technology. The agreement, signed in Hefei, Anhui province, will focus on joint research and development of high-performance core materials for next-generation solid-state batteries and tackle technical challenges associated with commercialization.
Building on a 13-year collaboration, the partnership aims to accelerate the transition of solid-state batteries into mass-produced electric vehicles within the next two years. Gotion emphasized that the effort will span multiple key materials and process innovations, with both companies contributing expertise in materials science and battery manufacturing.
Gotion has already commissioned a 0.2 GWh pilot line for its Gemstone all-solid-state battery, achieving a yield rate above 90% and an energy density of 300 Wh/kg. The Gemstone technology was first revealed at a technology conference in May 2024, marking the company’s entry into the all-solid-state battery sector.
According to Gotion’s development roadmap, small-scale production and vehicle integration trials for the Gemstone battery will commence in 2027, followed by mass production by 2030. Pan Ruijun, head of Gemstone research and development, stated that these timelines are designed to verify performance and manufacturing processes ahead of broader commercial deployment.
Several leading Chinese battery manufacturers have announced similar 2027 targets for pilot production of solid-state batteries, reflecting the industry’s push toward safer, higher-energy-density solutions. In 2025, Gotion ranked fifth among global electric vehicle battery suppliers, with a 4.5% market share and 53.5 GWh of installations, according to data from market research firm SNE Research.
By combining Gotion’s pilot production capabilities with BASF’s advanced materials portfolio, both companies aim to overcome critical barriers to large-scale solid-state battery manufacturing. The collaboration underscores growing momentum in the battery industry as stakeholders prepare for the next evolution in electric vehicle energy storage.
