Dover, Delaware, Sept. 29, 2025 — Sunrise New Energy Co., Ltd. (“Sunrise,” the “Company”) (NASDAQ: EPOW) announced today 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 achievement highlights the Company’s continuous leadership in developing high-performance lithium-ion battery anode materials.
This innovative methodology enhances both the initial Coulombic efficiency and power performance of graphite composites, offering a significant solution for the next generation of 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 prominence in the U.S. battery materials industry. This milestone is anticipated to boost the Company’s capacity for collaboration with North American partners and to establish more robust technological barriers and competitive advantages in the region.
The patented invention describes a novel procedure for preparing graphite-based composites utilizing titanium/nitrogen/fluorine co-doped porous titanium dioxide. The process includes: dispersing tetrabutyl titanate in a glycerol solvent, incorporating hexadecyl trimethyl ammonium bromide, and adjusting the pH with tetramethyl ammonium hydroxide; subsequently, ammonium fluoride solution is added, followed by heating at 150–200°C for 1–6 hours. The resulting substance is then centrifuged, washed, and vacuum-dried to yield the doped porous titanium dioxide. This material is then combined with lithium salts and graphite, spray-dried to produce porous lithium titanate-coated graphite composites, and subsequently carbonized in a tube furnace under argon protection.
“The issuance of this U.S. patent reinforces our dedication to advancing core technologies in anode materials, further supporting our strategic objective of ‘leading in the United States, expanding globally,’” stated Mr. Haiping Hu, Founder and CEO of Sunrise. “We are committed to increasing our R&D investments and accelerating the industrial deployment of our patented innovations.”
