Gotion High-tech has introduced its first experimental production line for Gemstone all-solid-state batteries, designed with a capacity of 0.2 GWh. The facility was officially launched on May 17 during the company’s 2025 technology conference.
The core equipment of this experimental production line is all locally produced, and the batteries have already been loaded on vehicles and road tested, according to Pan Ruijun, Gemstone’s head of research and development.
Gotion initially unveiled the Gemstone all-solid-state battery cell at its 13th science and technology conference on May 17, 2024. The Gemstone cell boasts an energy density of 350 Wh/kg or 800 Wh/L, representing a 40 percent increase compared to mainstream lithium ternary batteries. Following a year of validation, Gotion reported a 150 percent increase in the capacity of individual Gemstone cells, though specific capacity figures were not disclosed.
The company stated that the all-solid-state batteries have successfully passed various safety tests, including pin-prick, hot-box, overcharge, and crush tests. Pan Ruijun remarked, “This means that the human imagination of this ultimate battery is finally within reach.”
Gotion’s recent press release did not specify a timeline for the mass production of the all-solid-state batteries. In previous statements to media outlets, including CnEVPost, Pan indicated that small-volume production and vehicle trials for the all-solid-state batteries are expected to commence in 2027, with mass production targeted for 2030.
Currently, Gotion is one of the world’s largest electric vehicle (EV) battery manufacturers, holding a 3.5 percent share of the global market in the first quarter of the year, ranking it sixth according to South Korean market researcher SNE Research. Other major battery manufacturers are also planning small-volume production of all-solid-state batteries by 2027. For instance, CATL aims to begin such production within the same timeframe, as stated by the company’s chief scientist, Wu Kai, at an event on April 28, 2024.
On February 15, BYD’s battery business CTO Sun Huajun told a forum that the company expected to begin “demonstration applications” of all-solid-state batteries around 2027.
