Insights
Granted patent formalizes a specific anode preparation route; it strengthens IP but commercial impact remains uncertain.
The patent documents a reproducible process for anode material manufacture, spanning coke pulverization, low‑temperature graphitization (2000–2600°C, 6–24 hours), lithium supplementation, pre‑carbonization (300–400°C) and vapor deposition (800–1100°C). This creates a clear technical pathway to produce graphite‑based anodes that the company reports have high first‑cycle efficiency, high‑temperature storage performance, and strong cycling stability.
Commercial value depends on several dependencies and risks. Adoption requires scale‑up of high‑temperature graphitization and vapor deposition steps, reliable control of particle distributions (D50 and D90/D10 criteria), supply of isotropic petroleum coke, and integration into cell manufacturing lines; none of those operational or cost details are disclosed. The patent protects a method but does not by itself prove manufacturing economics or market uptake.
Watch for near‑term milestones that reveal commercial traction: pilot or commercial production starts, qualification results from battery makers, and any licensing deals; monitor developments across the next
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.”
