Insights
Sunrise's patented silicon-carbon anode technology solves key ionic conductivity challenges, positioning them advantageously in the high-growth solid-state battery market.
The patent granted to Sunrise represents a significant technological advancement in silicon-carbon composite anode materials. Silicon-carbon anodes are crucial for next-generation batteries as they offer substantially higher theoretical capacity than conventional graphite anodes (approximately 10x higher for silicon).
The innovation addresses two critical technical challenges that have limited widespread adoption: poor ionic conductivity and insufficient compressive strength for high-pressure solid-state battery assembly processes. By developing a fast-ion conductor coating, Sunrise has created a solution that enhances both ionic transport and mechanical robustness.
This patent positions Sunrise strategically in the solid-state battery value chain. Solid-state batteries represent a paradigm shift in energy storage, offering improved safety (eliminating flammable liquid electrolytes), higher energy density (potentially 2-3x current lithium-ion), and longer cycle life. Market projections suggest solid-state technology could capture significant market share by 2030-2035.
The innovation's value extends beyond just incremental improvement—it potentially enables commercial viability for an emerging battery architecture. While many companies focus on solid electrolytes, Sunrise has tackled the equally important anode compatibility issue, demonstrating technical foresight by addressing a critical bottleneck in the solid-state battery manufacturing process.
This intellectual property could translate to licensing opportunities, manufacturing advantages, or partnership potential with major battery and automotive manufacturers who are heavily investing in solid-state technology.
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.”
