DOVER, USA, Oct. 07, 2025 (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 been granted authorization registration for its invention patent titled “Preparation Method of Anode Material for Energy Storage Lithium-Ion Batteries.” This achievement further reinforces Sunrise’s global leadership in advanced energy storage battery anode materials .

The resulting anode material demonstrates excellent high-temperature storage performance, high first-cycle efficiency, and outstanding cycling stability , providing significant advantages for energy storage lithium-ion batteries and supporting the development of high-performance, long-life energy storage systems worldwide.

The invention discloses a method for preparing anode materials used in energy storage lithium-ion batteries. The process includes pulverizing isotropic petroleum coke to a particle size of D50 = 10–50 μm; performing low-temperature graphitization at 2000–2600°C for 6–24 hours; crushing, classifying, and removing fine powders to obtain a graphite precursor with a particle size distribution of D90/D10 ≤ 4. Metallic lithium and polymers are then added to an organic solvent, filtered, and vacuum dried to obtain a lithium supplementing agent. The graphite precursor, lithium supplementing agent, and binder are uniformly mixed in a ball mill, pre-carbonized at 300–400°C for 1–6 hours to form secondary granules, and finally heated to 800–1100°C under an inert atmosphere with a carbon source gas for vapor deposition for 1–6 hours to obtain the finished product.

“This patent reflects our R&D team’s strong innovation capacity and further validates Sunrise’s globally leading position in advanced energy storage anode materials,” said Haiping Hu , Founder and CEO of Sunrise New Energy. “We will continue to enhance our R&D investment and accelerate the industrial application of high-efficiency anode materials for the rapidly expanding global energy storage market.”
