Sunrise New Energy develops advanced CVD system for silicon-carbon anodes

DOVER, USA - Sunrise New Energy Co., Ltd. (NASDAQ:EPOW), a small-cap company with a market value of $40.68 million that has seen its stock surge over 43% in the past six months, announced Thursday that its subsidiary has co-developed a chemical vapor deposition (CVD) fluidized bed system for silicon-carbon anodes in partnership with Songci Electromechanical Technology Co., Ltd.

The new system aims to address challenges in uniformity and consistency that have traditionally limited CVD processes in silicon-carbon composite material production, according to the company’s press release.

Sunrise New Energy claims the technology features improved deposition and coating uniformity, precise temperature and concentration control, and AI-enabled management capabilities. The company states that the system enhances product performance in energy density, first-cycle efficiency, and cycling stability.

The collaboration combines Sunrise’s expertise in anode materials with Songci Electromechanical’s manufacturing capabilities. Songci is a holding subsidiary of AUTEWEI Technology Co., Ltd., which operates in the photovoltaic and semiconductor equipment sectors.

Sunrise New Energy, headquartered in Zibo, China, manufactures graphite anode material for lithium-ion batteries through its joint venture. The company has a production facility in Guizhou Province with a reported capacity of 50,000 tons.

The company’s founder and CEO, Haiping Hu, has been involved in the graphite anode industry since 1999, according to the press release statement.

In other recent news, Sunrise New Energy Co., Ltd. announced significant developments that may interest investors. The company has secured a $29 million supply contract with China Sodium Times (Shenzhen) New Energy Technology Co., Ltd., under which its subsidiary will provide 10,000 tons of artificial graphite anode materials over the next year. Additionally, Sunrise New Energy received $600,000 in funding from the National Special Fund for Science and Technology Development for a project marking a notable achievement in the Qianxinan Prefecture. The company has also been granted two patents in China for innovative anode materials. One patent covers a preparation method for mesophase carbon microsphere-silicon carbon composite anode material, while the other addresses limitations in current silicon-carbon composites used in lithium-ion batteries. These patents reflect the company’s ongoing commitment to advancing battery technology. These recent developments highlight Sunrise New Energy’s focus on innovation and strategic partnerships.
