Chinese battery manufacturer Gotion High-tech has signed a strategic cooperation agreement with Germany’s BASF to push forward solid-state battery technology. The deal, inked in Hefei, Anhui province, focuses on joint R&D of high-performance core materials for next-generation solid-state batteries and aims to tackle the technical hurdles standing in the way of commercialization.
Building on more than a decade of collaboration, the two companies are now aiming to fast-track the integration of solid-state batteries into mass-produced electric vehicles—targeting a two-year window for the transition. Gotion says the initiative will span innovations in materials and processes, drawing on both firms’ expertise in materials science and battery manufacturing.
Gotion has already launched a pilot production line for its flagship all-solid-state battery, Gemstone, with an annual capacity of 0.2 GWh. The line reportedly boasts a yield rate of over 90% and an energy density of 300 Wh/kg. The Gemstone technology was first unveiled at a company tech conference in May 2024, marking Gotion’s official entry into the all-solid-state arena.
According to Gotion’s development roadmap, small-scale production and vehicle integration trials are scheduled to begin in 2027, with mass production targeted for 2030. Pan Ruijun, head of Gemstone R&D, said the timelines are designed to thoroughly validate both performance and manufacturing processes ahead of large-scale deployment.
Gotion is not alone in racing toward 2027—several top Chinese battery makers have announced similar pilot production targets, reflecting the broader industry push toward safer, higher-energy-density solutions. In 2025, Gotion ranked fifth globally among EV battery suppliers, holding a 4.5% market share with 53.5 GWh installed, according to SNE Research.
By pairing Gotion’s pilot-scale production capabilities with BASF’s advanced materials know-how, the two partners hope to break through key barriers to mass manufacturing of solid-state batteries. The collaboration underscores the growing momentum in the battery sector as players prepare for the next leap in EV energy storage technology.
