Sunrise New Energy secures Japanese patent for anode material preparation method

Sunrise New Energy announced that its patent application for the invention titled “Method for Preparing Anode Material for Lithium-Ion Batteries” has been approved by the Japanese Patent Office. The patent, with the number “Invention 2022-170556,” was granted on December 20, 2023, and is valid for 20 years. The patent was issued by a Japanese Ministry of Economy, Trade and Industry official. This invention provides a method for preparing lithium-ion battery anode material that enhances the initial efficiency and power of graphite composite materials. The method not only meets the requirements for high energy density in lithium-ion battery anode materials but also improves the fast-charging capabilities. It effectively enhances the rate, safety, and cycling of graphite anode materials while overcoming the limitations of low initial efficiency and insignificant power performance seen in existing preparation methods.
