Chinese battery maker Gotion High-Tech has launched the first road testing for its next-generation all-solid-state batteries, after completing the country's first fully localized 0.2 Gigawatt-hour pilot line, marking a milestone in the global race to commercialize next-generation EV powers.

Pan Ruijun, research and development director of the company's all-solid-state project, said on Saturday that Gotion's all-solid-state batteries Jinshi has completed a 0.2 gigawatts production line, which was the first in China, with all equipment fully localized.

The prototype cells, already undergoing vehicle-mounted road tests, feature a 150 percent increase in energy capacity and a 90 percent reduction in preloading force after 12 months of extreme condition validation, including nail penetration, thermal chamber and overcharge scenarios.

In a parallel move, Gotion's Chief Scientist Zhu Xingbao said the company is planning a 12 GWh quasi-solid-state battery production line.

With an energy density of 300 Wh/kg, the battery enables EV ranges of more than 1,000 kilometers, Zhu said.

He emphasized, "Such an advanced battery has already logged over 10,000 kilometers in road tests."
