Insights
Sunrise's new US patent for lithium-ion battery anode material strengthens its IP portfolio and technical competitive position in the growing EV battery market.
This newly granted US patent (No. 12,371,341 B2) represents a significant technological milestone for Sunrise New Energy in the lithium-ion battery materials space. The patent covers an innovative preparation method for graphite-based anode materials that incorporates titanium/nitrogen/fluorine co-doped porous titanium dioxide. What makes this technology particularly valuable is its ability to enhance two critical battery performance metrics: initial Coulombic efficiency and power performance of graphite composites.
From a technical perspective, the patented method addresses key challenges in anode material design. The multi-step process involving tetrabutyl titanate, glycerol solvent, and specific chemical additives creates a specialized coating that likely improves electron transfer at the electrode interface while maintaining structural integrity. These improvements directly translate to batteries with potentially higher energy density and faster charging capabilities - both critical performance factors for electric vehicle applications and grid storage systems.
This patent strengthens Sunrise's position in the highly competitive US battery materials market at a time when domestic battery supply chains are receiving unprecedented attention and investment. Securing US intellectual property protection aligns with their stated strategy of "leading in the United States, expanding globally" and positions them to pursue partnerships with North American battery manufacturers and OEMs who are rapidly expanding production capacity. This technological differentiation could be particularly valuable as battery makers seek performance advantages while controlling costs in an increasingly commoditized market.
Dover, Delaware, Sept. 29, 2025 (GLOBE NEWSWIRE) -- Sunrise New Energy Co., Ltd. (“Sunrise”, the “Company”, “we” or “our”) (NASDAQ: EPOW), is pleased to announce that its subsidiary, Sunrise (Guizhou) New Energy Material Co., Ltd. (formerly Huiyang (Guizhou) New Energy Materials Co., Ltd.), has been granted U.S. Patent No. US 12,371,341 B2, titled “Preparation Method of an Anode Material for Lithium-Ion Batteries.” This milestone underscores the Company’s continued leadership in high-performance lithium-ion battery anode material innovation.
This innovative method improves both the initial Coulombic efficiency and power performance of graphite composites, offering a breakthrough solution for next-generation high-energy and high-power lithium-ion batteries. By securing this intellectual property, Sunrise not only strengthens its global patent portfolio but also demonstrates its technical leadership in the U.S. battery materials sector. This achievement is expected to enhance the Company’s ability to collaborate with North American partners and to build stronger technology barriers and competitive advantages in the region.
The patented invention discloses a novel method for preparing graphite-based composites through titanium/nitrogen/fluorine co-doped porous titanium dioxide. The process includes: dispersing tetrabutyl titanate in a glycerol solvent, adding hexadecyl trimethyl ammonium bromide, and adjusting the pH with tetramethyl ammonium hydroxide; followed by adding ammonium fluoride solution and heating at 150–200°C for 1–6 hours. The resulting product is centrifuged, washed, and vacuum-dried to obtain the doped porous titanium dioxide. This material is then combined with lithium salts and graphite, spray-dried to form porous lithium titanate-coated graphite composites, and subsequently carbonized in a tube furnace under argon protection.
“The granting of this U.S. patent reaffirms our commitment to advancing core technologies in anode materials ,further supporting our strategic vision of ‘leading in the United States, expanding globally,’” said Mr. Haiping Hu, Founder and CEO of Sunrise. “We will continue to increase our R&D investments and accelerate the industrial application of our patented innovations.”
