Chinese solid-state battery start-up Pure Lithium New Energy has raised tens of millions of yuan in fresh Pre-A+ funding, as it moves from pilot work into early production.
Chinese tech news site 36Kr reported that the round was backed by Yizhuang Guotou, with Yundao Capital as exclusive financial adviser. The funds would go towards product development, market expansion and production-line rollout.
Pure Lithium was founded in May 2022 and develops all-solid-state batteries using a self-developed organic-inorganic composite solid electrolyte and a supercritical coating process. The company said the approach improves contact between the solid electrolyte and electrodes, a core difficulty in all-solid-state battery production.
The company built a pilot line in Beijing’s Yizhuang development zone in April 2023, followed by a 500 MWh line in Lankao county, Henan, the next month. It began mass production of 50 Ah all-solid-state cells in October 2024.
Pure Lithium is starting with energy storage rather than passenger EVs. It is also testing batteries in low-speed electric vehicles, including a Beijing Yizhuang two-wheeler battery-swap pilot.
The 500 MWh line has reached its planned capacity, while a GWh-level line is under construction and expected to start production in 2026. Pure Lithium expects revenue of more than 100 million yuan this year.
