The company disclosed the update in a recent 36Kr report, which also said Pure Lithium recently completed a Pre-A+ financing round worth tens of millions of yuan. From pilot line to mass production Founded in May 2022, Pure Lithium focuses on all-solid-state battery development using self-developed organic-inorganic composite electrolytes and a supercritical coating process. The company completed a 10Ah pilot production line in Beijing Yizhuang in April 2023, followed one month later by the start of construction of a 500 MWh production line in Henan. In October 2024, it announced mass production of 50Ah all-solid-state battery cells. Pure Lithium said its first-generation products passed CNAS-certified GB/T36276-2018 testing, with an average weight loss rate of 0.023%. The company demonstrated battery-cutting tests at CIBF 2026 in Shenzhen, where all-solid-state cells continued powering external devices after being physically cut, according to OFweek. Composite electrolyte approach Pure Lithium’s first-generation batteries use lithium-iron phosphate cathodes and graphite anodes, with an energy density of 180–190 Wh/kg. The company said next-generation products under development are targeting energy density above 200 Wh/kg. Founder Yang Fan said the company developed ternary copolymer materials and new oxide materials to improve conductivity and interface stability between solid electrolytes and electrodes. The company stated that its batteries currently achieve a cycle life of 6,000 to 8,000 cycles with a rate capability above 1C. Storage and swapping prioritised Pure Lithium said it is prioritising the commercialisation of energy storage and low-speed mobility applications before expanding further into passenger EV markets. Projects with State Power Investment Corporation, State Grid, and Jingneng Group have already entered deployment stages, according to the company. The company also said its “Thermal Pipeline Power Project” has been operating for over 12 months, marking one of its longest-running field deployments of all-solid-state batteries in infrastructure energy storage applications. In June 2025, the company launched a two-wheel battery swap demonstration project in Beijing Yizhuang, involving 1,500 all-solid-state batteries, 1,000 vehicles, and 100 battery swap cabinets. Yang Fan said some vehicles in the pilot project achieved up to 100 km of range, compared with around 30–50 km previously using liquid-electrolyte battery packs. Industry context China’s solid-state battery sector continues to expand as automakers and battery companies accelerate pilot production and commercialisation efforts. Earlier this year, a GAC-backed company said it was targeting mass-producible solid-state batteries in 2026, while BYD chief scientist Lian Yubo said the industry remains at a “critical breakthrough stage” with commercialisation constraints still unresolved. According to China EV DataTracker, total EV battery installations reached 62.4 GWh in April 2026, up 15.3% year-on-year. LFP batteries accounted for 50.8 GWh, representing 81.4% of the market, while ternary NMC batteries accounted for 11.5 GWh and 18.4% of the market. Pure Lithium said its GWh-scale production line is expected to enter operation during 2026 with capacity exceeding 1 GWh. The company also targets annual revenue above 100 million yuan (14.7 million USD) in 2026. Battery installations for EVs in China till Aptil 2026. Credit: China EV DataTracker
