Volkswagen-backed Gotion starts all-solid-state battery pilot production
Gotion High-Tech commenced pilot production of all-solid-state batteries at its Hefei facility, achieving self-reliance with local equipment. Backed by Volkswagen, Gotion aims for large-scale electric vehicle solutions with 0.2 GWh capacity and 350 Wh/kg energy density. The batteries show a 90% yield rate and improved material stability, addressing reactivity issues as they begin testing in passenger vehicles.
Key points
- Gotion High-Tech has begun pilot production of all-solid-state batteries as of May 17.
- The production site is in Hefei, China, using domestically sourced core equipment.
- Gotion has a production capacity of 0.2 GWh for testing Jinshi all-solid-state batteries.
- The batteries have an energy density of 350 Wh/kg at the cell level.
- A high yield rate of 90% for the produced batteries has been achieved.
- These batteries use solid sulfides, which have high ionic conductivity but potential reactivity with air.
- Material stability has improved from 79% to 95%, reducing safety risks.
- Initial testing of the batteries is underway in passenger electric vehicles.
Why it matters
- The development aligns with the global push for greener energy solutions and advancements in battery technology.
- The trend of moving towards solid-state batteries reflects increasing demand for longer-lasting electric vehicle solutions.
- Gotion's initiative may impact the competitive landscape in the EV battery market, particularly against established players like Toyota.
Gotion's progress in all-solid-state battery production marks a significant milestone in EV technology, enhancing both energy efficiency and safety, with the potential to influence the future of electric vehicles globally.
