Sunrise New Energy Announces Hard Carbon Composite Material Patent for Solid-State and Low-Temperature Energy Storage Batteries
DOVER, USA, Dec. 10, 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 published a patent titled “Spherical Hard Carbon Composite Material and Its Preparation Method”, with the patent number CN2025106204848. The invention targets hard carbon composite anode materials used in low-temperature energy storage batteries, particularly sodium-ion batteries, and is expected to provide more efficient and reliable material solutions for large-scale energy storage systems as well as commuter and remote-area power infrastructure.
The technology addresses common challenges of traditional hard carbon anode materials—such as reduced efficiency, limited cycle life, and capacity degradation under low-temperature and high-rate charge/discharge conditions—by designing a spherical hard carbon composite structure, optimizing the carbon framework and conductive/ionic pathways, and improving surface and interfacial treatments. These innovations aim to enhance low-temperature conductivity, ion diffusion efficiency, and structural stability, enabling superior capacity retention, high-rate performance, and cycling durability in sodium-ion and broader energy storage battery applications.
“This technology will further enhance our portfolio of advanced energy storage materials and strengthen the Company’s competitiveness in the global energy storage market, while also expanding into low-temperature sodium-ion storage solutions,” said Haiping Hu, Founder and CEO of Sunrise. “We will continue to advance engineering validation, performance testing, and industrialization efforts for this patented technology, with the objective of accelerating the commercialization of high-performance battery materials.”
