    DOVER, USA, Oct. 02, 2025 (GLOBE NEWSWIRE) -- Sunrise New Energy Co., Ltd. ("Sunrise", the "Company", "we" or "our") (NASDAQ:EPOW) today announced that its subsidiary, Sunrise (Guizhou) New Energy Materials Co., Ltd., has been granted an invention patent titled "Preparation Method of a Fast-Ion-Conductor–Coated Silicon-Carbon Anode Composite Material" (Patent No. ZL 2022 1 0396110.9; grant publication No. CN11482237B).

    Silicon-carbon anode materials are considered the most promising solution to increase the energy density of lithium-ion batteries, owing to the combination of high capacity and excellent first-cycle efficiency. They are also regarded as the leading candidates for large-scale application in solid-state batteries, which are widely seen as the next-generation energy storage technology due to the advantages of higher safety, greater energy density, and longer cycle life compared with conventional lithium-ion batteries.

    However, existing CVD-based silicon-carbon composites face key limitations: the rigid porous carbon framework and the soft secondary carbon coatings cannot withstand the high-pressure assembly required for solid-state cells. While such coatings provide strong electrical conductivity, ionic conductivity remains poor, which restricts large-scale utilization in solid-state applications.

    The newly granted patent from Sunrise addresses this bottleneck. By introducing a fast-ion conductor coating, the process significantly improves the ionic transport characteristics of silicon-carbon composites while simultaneously enhancing compressive strength. This innovation secures a critical enabling technology for solid-state battery manufacturing and provides strong technical support for the large-scale deployment of silicon-carbon anodes in solid-state batteries.

    "This patent reinforces the Company's leadership in advanced anode technologies and underpins its role in enabling the commercialization of solid-state batteries," said Haiping Hu, Founder and CEO of Sunrise. "The Company remains committed to increasing R&D investment and accelerating the industrialization of pioneering anode technologies."
