ZIBO, China, Dec. 29, 2023 (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 received preliminary approval from the National Intellectual Property Office for its invention patent titled "Preparation Method of Metal Sulfide-Doped Hard Carbon Composite Material". The official document number assigned is 2023121500112460. This invention falls within the field of secondary battery material preparation, focusing on the preparation method for a metal sulfide-doped hard carbon composite material.

Sodium-ion batteries predominantly utilize hard carbon materials as the anode material. However, these materials suffer from several noticeable drawbacks, including low specific capacity, low compactness, and limited expansion. Moreover, the inherent disparity in electronic conductivity of the material leads to performance variations in terms of rate capability. As a high-capacity anode material, metal sulfides need to be mixed or doped with other carbon-based materials exhibiting high initial efficiency and excellent cycling performance to enhance the overall performance. The objective of Sunrise’s invention is to provide a preparation method for a metal sulfide-doped hard carbon composite material that enhances the specific capacity and power performance of hard carbon.

"Sunrise, a research-driven high-tech enterprise, stands at the forefront of the global battery anode materials industry, boasting cutting-edge technology. We have filed both domestic and international patents related to groundbreaking technologies in graphite, silicon-carbon, and hard carbon. Our technological leadership enables us to establish exclusive partnerships with renowned companies in electric vehicle and energy storage battery production.” commented Mr. Haiping Hu, the Chairman of the Company. “Moving forward, we remain committed to advancing our research and development endeavors, as well as manufacturing lithium-ion and sodium-ion battery anode materials, to provide our esteemed customers with comprehensive and innovative solutions."
