Gotion High‑Tech, supported by Volkswagen, has completed the design phase for its first 2GWh all‑solid‑state battery mass‑production line, marking a significant step towards commercial rollout.
The company confirmed the update through its investor platform, according to news outlet CarNewsChina, signalling a move from pilot‑scale validation to full industrial planning for its “Jinshi” solid‑state technology. The Jinshi cell uses a sulphide‑based solid electrolyte and delivers an energy density of 350Wh/kg, around 40% higher than mainstream ternary lithium‑ion batteries. Technical details shared at Gotion’s 2025 Global Technology Conference highlighted a potential 1,000 km range per charge and stable operation between -40°C and 80°C.
Its existing 0.2GWh pilot line has already reached a 90% yield rate for its solid-state battery, using fully domestic core equipment and in‑house production architecture. Safety testing showed the cells withstanding 200°C thermal chamber exposure and 3mm steel needle penetration without ignition or explosion. Gotion ranked fifth globally for power battery installations in 2025, reaching 53.5 GWh and a 4.5% market share, reflecting an 82.5% year‑on‑year increase. In China, its 2024 market share stood at 5%. By comparison, CATL expects small‑scale solid‑state production to begin in 2027.
The 2 GWh line follows the launch of Gotion’s “G‑Yuan” semi‑solid‑state battery in 2025, offering 300Wh/kg and backed by a planned 12GWh production capacity to bridge the transition to full solid‑state commercialisation. Volkswagen holds a 25% stake in the company, and both Volkswagen and Audi have issued letters of intent for future supply. Gotion aims for small‑batch vehicle integration by the end of 2026, with mass production targeted for 2030. Investment for the new facility is estimated at 3–4 billion yuan, and the company’s global plans include more than 100GWh of overseas capacity across Europe, North America and Southeast Asia.
