DOVER, USA, Oct. 02, 2025 — Sunrise New Energy Co., Ltd. (NASDAQ: EPOW), referred to as “Sunrise” or the “Company,” announced today that its subsidiary, Sunrise (Guizhou) New Energy Materials Co., Ltd., has been issued an invention patent. The patent, titled “Preparation Method of a Fast-Ion-Conductor–Coated Silicon-Carbon Anode Composite Material,” carries Patent No. ZL 2022 1 0396110.9 and grant publication No. CN11482237B.
Silicon-carbon anode materials represent a highly promising solution for boosting the energy density of lithium-ion batteries, primarily due to their high capacity and excellent first-cycle efficiency. These materials are also considered prime candidates for broad adoption in solid-state batteries. Solid-state batteries are widely recognized as the next-generation energy storage technology, offering significant advantages over conventional lithium-ion batteries, including enhanced safety, superior energy density, and extended cycle life.
Nevertheless, current CVD-based silicon-carbon composites encounter significant limitations. Their rigid porous carbon framework and soft secondary carbon coatings are unable to endure the high-pressure assembly demands of solid-state cells. Although these coatings offer robust electrical conductivity, their ionic conductivity is notably poor, thereby hindering widespread adoption in solid-state applications.
The patent recently awarded to Sunrise directly addresses these challenges. By incorporating a fast-ion conductor coating, the patented method substantially improves the ionic transport properties of silicon-carbon composites while concurrently boosting their compressive strength. This breakthrough innovation establishes a crucial enabling technology for solid-state battery production and offers robust technical backing for the extensive deployment of silicon-carbon anodes within solid-state batteries.
“This patent solidifies the Company’s leadership in advanced anode technologies and underscores its pivotal role in advancing the commercialization of solid-state batteries,” stated Haiping Hu, Founder and CEO of Sunrise. “Sunrise is dedicated to increasing its R&D investments and expediting the industrialization of our pioneering anode technologies.”
