Golden Feather New Energy (founded 2017, Beijing) develops lithium‑metal all‑solid‑state, quasi‑solid‑state, and semi‑solid batteries with reported energy densities up to 550 Wh/kg. Targets drones, eVTOL/aircraft, commercial EVs, industrial systems.
Golden Feather New Energy (Zhejiang Golden Feather New Energy Technology Co., Ltd.), founded in 2017 and headquartered in Beijing, China, was established by PhD graduates from Peking University, Columbia University, and Arizona State University. GF Energy develops and industrializes lithium‑metal battery technologies — all‑solid‑state, quasi‑solid‑state (anode‑free), and semi‑solid — with a focus on commercial‑scale production, safety, and fast charging. The company operates R&D and pilot manufacturing centers in Hangzhou and Huzhou and aims to accelerate adoption of high‑energy‑density batteries for e‑mobility, drones, and industrial systems.
GF Energy develops lithium‑metal cells across all‑solid, quasi‑solid (anode‑free), and semi‑solid formats. Core innovations include a hybrid polymer–oxide solid electrolyte produced in continuous film lines, a self‑forming lithium anode on copper collectors with electrolyte mass below 4%, adaptive interface self‑healing, and self‑limiting pressure regulation to preserve electrode contact. Reported performance includes gravimetric energy densities above 550 Wh/kg and volumetric densities over 1200 Wh/L, fast charge capability, and extended cycle life. A proprietary computational material‑optimization system guides electrolyte and interface chemistry for improved safety and manufacturability.
Product lines include the ‘Infinity’ cylindrical series (all‑ and quasi‑solid), the ‘Shanhai’ all‑solid series, anode‑free lithium‑metal cells, and large‑format packs up to 600 kWh. Offerings deliver high gravimetric and volumetric energy, fast charge, wide temperature operation, and high power (up to 10C continuous, 20C peak). Target industries: drones, eVTOL and electric aircraft, commercial EVs, industrial power systems, and wearables.
In 2025 GF Energy delivered the first all‑solid‑state ‘Infinity’ cylindrical batteries to international customers (September 2025) and launched the ‘Shanhai’ series with small‑batch deliveries and planned mass production at the Hangzhou facility in Q4 2025. The company is also constructing a 10 GWh battery and energy storage headquarters in Dongguan to expand manufacturing capacity. Collaborations include joint laboratories with Peking University and ongoing pilot lines in Hangzhou and Huzhou.
GF Energy has completed multiple financing rounds totaling several hundred million yuan, most recently a Series A‑II. Strategic and financial backers include State Power Investment Corporation, the Peking University Scientific Achievement Transformation Fund, GGR Capital, Hongnuo Ventures, Qingzi Zeyuan Capital, Nine Intelligence Capital, and JiuZhi Capital.
