Sunrise Secures Patent for Energy Storage Lithium-Ion Battery Anode Material, Fortifying Global Leadership in Advanced Energy Storage

Posted on by

DOVER, USA, Oct. 07, 2025 – Sunrise New Energy Co., Ltd. (NASDAQ: EPOW), also referred to as “Sunrise” or “the Company,” today announced that its subsidiary, Sunrise (Guizhou) New Energy Materials Co., Ltd., has successfully obtained authorization registration for its invention patent, **“Preparation Method of Anode Material for Energy Storage Lithium-Ion Batteries.”** This accomplishment further establishes Sunrise’s **global preeminence in advanced materials for energy storage battery anodes**.

The anode material produced through this method exhibits **superior high-temperature storage capabilities, impressive first-cycle efficiency, and remarkable cycling longevity**. These characteristics offer substantial benefits for **lithium-ion batteries used in energy storage**, thereby fostering the advancement of high-performance, durable energy storage solutions globally.

This invention details a procedure for manufacturing anode materials intended for energy storage lithium-ion batteries. The methodology involves grinding isotropic petroleum coke to achieve a particle size of D50 = 10–50 μm, followed by low-temperature graphitization carried out at 2000–2600°C for 6–24 hours. Subsequently, the material undergoes crushing, classification, and fine powder removal to yield a graphite precursor with a particle size distribution where D90/D10 ≤ 4. Next, metallic lithium and polymers are introduced into an organic solvent, filtered, and vacuum-dried to create a lithium supplementing agent. The graphite precursor, lithium supplementing agent, and a binder are then thoroughly blended in a ball mill, followed by pre-carbonization at 300–400°C for 1–6 hours to form secondary granules. The final step involves heating these granules to 800–1100°C in an inert atmosphere, utilizing a carbon source gas for vapor deposition over 1–6 hours, to produce the ultimate finished product.

“This patent underscores our R&D team’s robust innovation capabilities and reaffirms Sunrise’s global leadership in advanced anode materials for energy storage,” stated **Haiping Hu**, Founder and CEO of Sunrise New Energy. “We are committed to increasing our R&D expenditures and fast-tracking the commercial deployment of highly efficient anode materials to meet the demands of the rapidly growing global energy storage sector.”
