Volkswagen-backed Gotion High-Tech has completed the design phase for its first 2GWh all-solid-state battery production line, signaling a significant step toward commercializing this next-generation battery technology. The move positions Gotion ahead of competitors like CATL, which plans small-scale solid-state production starting in 2027.
Key Technical Specifications
Gotion’s “Jinshi” battery utilizes a sulfide-based solid electrolyte, achieving an energy density of 350 Wh/kg – a 40% increase over conventional ternary lithium-ion cells. This higher density translates to a projected range of 1,000 km (620 miles) per charge. The battery also demonstrates robust thermal stability, operating reliably between -40°C and 80°C.
Notably, Gotion’s pilot line has already achieved a 90% yield rate, with all core equipment sourced domestically and the line architecture developed in-house. Safety tests confirm the battery’s stability, passing rigorous trials including 200°C thermal exposure and steel needle penetration without combustion or explosion.
Market Context and Competitive Landscape
In 2025, Gotion ranked fifth globally in power battery installations, deploying 53.5 GWh with a 4.5% market share – an 82.5% year-over-year increase. Within China, the company held a 5% share in 2024.
This rapid growth, coupled with Volkswagen’s 25% ownership stake and secured supply agreements, underscores Gotion’s strategic importance in the future of EV battery technology.
To bridge the gap between current lithium-ion production and full solid-state commercialization, Gotion launched its “G-Yuan” semi-solid-state battery in 2025, boasting 300 Wh/kg density, and plans a 12GWh production capacity for this technology.
Investment and Timeline
The 2GWh solid-state facility is estimated to cost 3-4 billion yuan ($414-552 million USD), aligning with industry benchmarks of 1.5-2 billion yuan per GWh for advanced battery lines. Gotion intends to integrate these batteries into vehicles in small batches by late 2026, with full-scale mass production targeted for 2030. The company is also expanding its manufacturing footprint globally, planning over 100 GWh of capacity across Europe, North America, and Southeast Asia.
The aggressive timeline and Volkswagen’s commitment suggest solid-state batteries are rapidly moving from the laboratory to the factory floor. This transition will likely reshape the EV landscape, potentially offering longer ranges, improved safety, and faster charging capabilities.
