Sunrise New Energy granted patent for silicon-carbon anode technology

DOVER, USA - Sunrise New Energy Co., Ltd. (NASDAQ:EPOW), whose stock has surged over 24% in the past week according to InvestingPro data, announced Thursday that its subsidiary has been granted an invention patent for a preparation method of fast-ion-conductor coated silicon-carbon anode composite material.

The patent (No. ZL 2022 1 0396110.9) addresses limitations in current silicon-carbon composites used in lithium-ion batteries. According to the company’s press release statement, existing CVD-based silicon-carbon composites face challenges with rigid porous carbon frameworks and soft secondary carbon coatings that cannot withstand high-pressure assembly required for solid-state cells. The company, currently valued at $37.51 million, has shown impressive revenue growth of 44% over the last twelve months.

The newly patented technology introduces a fast-ion conductor coating that improves ionic transport characteristics while enhancing compressive strength of silicon-carbon composites.

Silicon-carbon anode materials are considered promising for increasing energy density in lithium-ion batteries due to their high capacity and first-cycle efficiency. They are also viewed as leading candidates for application 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.

Sunrise New Energy, headquartered in Zibo, Shandong Province, China, is engaged in manufacturing graphite anode material for lithium-ion batteries through its joint venture. The company operates a manufacturing facility in Guizhou Province with a production capacity of 50,000 tons. While the company’s stock has gained nearly 49% over the past six months, InvestingPro analysis reveals several financial challenges, with 12 additional key insights available to subscribers.

In other recent news, Sunrise New Energy Co., Ltd. has reported several significant developments. The company announced that its subsidiary has been granted a U.S. patent for a new method of preparing anode material for lithium-ion batteries, which aims to enhance efficiency and power performance. Similarly, Sunrise New Energy has secured patents in Japan and Korea for its innovative manufacturing and preparation methods of graphite-based anodes. These patents are expected to improve the efficiency, cycle life, and power performance of the materials.

Additionally, Sunrise New Energy has received a $137,000 grant from the Guizhou Provincial Department of Science and Technology. This funding will support the establishment of a Provincial Science and Technology Innovation Leading Talent Workstation for New Energy Battery Materials. Furthermore, the company announced plans to develop a 1GW lithium battery pack project in the United States through its subsidiary, Alchemistica Incorporated. This initiative targets the growing demand for energy storage batteries in the U.S. and North American markets.
