HidFunc was founded in December 2023 as a spinout from Fudan University to commercialize anode-free sodium battery technology developed by co-founder and chief scientist Wang Fei. The company offers a sodium battery platform with distinct high-power (“High Speed”) and high-energy (“Hidden Peak”) product lines targeting markets from consumer electronics and power tools to electric vehicles and stationary storage. Its High Speed series has already entered China’s leading tier of sodium battery suppliers by shipment, while Hidden Peak products are undergoing qualification tests with multiple passenger and commercial vehicle manufacturers. Management cites manufacturing yield and consistent large-scale production as the primary commercialization challenge and is using electrochemical modeling to optimize processes. HidFunc plans to use the latest funding to build new production lines and further develop its platform as it scales toward gigawatt-hour manufacturing. The company has attracted backing from both venture capital and strategic industry investors, including previous support from Luminous Ventures, SoftBank China, and IDG Capital.
