DOVER, USA, Oct. 06, 2025 — Sunrise New Energy Co., Ltd. (“Sunrise,” the “Company,” “we,” or “our”) (NASDAQ: EPOW) announced today that its subsidiary, Sunrise (Guizhou) New Energy Materials Co., Ltd., has been awarded an invention patent titled “Preparation Method of a Mesophase Carbon Microsphere–Silicon Carbon Composite Anode Material” (Patent Granted No. CN115188949B). This recently issued patent represents a significant technological advancement in solid-state battery anode materials, reinforcing Sunrise’s leading position in the realm of next-generation solid-state battery technologies and furthering its innovation trajectory in high-performance energy materials.
The patented invention outlines an innovative procedure for creating mesophase carbon microsphere–silicon carbon composite anode materials. The method involves polymerizing medium-temperature pitch within a reactor to produce polymerized pitch, followed by sedimentation and centrifugation to yield mesophase carbon microspheres. These microspheres then undergo modification using plasma technology to form modified mesophase carbon microspheres. An organic solvent, containing an organosilane coupling agent and organic lithium salt, is prepared, and silicon salts are deposited onto the modified microsphere surface via an electrochemical deposition technique. This is succeeded by washing and carbonization steps to obtain the final composite material.
This patented technology holds a crucial role in the progression of solid-state batteries. The newly developed composite material exhibits superior lithium-ion transport, structural stability, and compressive strength, thereby significantly boosting the energy density, cycle life, and safety of solid-state batteries. By optimizing the structural interface between carbon and silicon, the technology effectively addresses the challenges of volume expansion and ionic conductivity encountered by silicon-based anodes during high-pressure solid-state battery assembly, providing essential technical backing for the large-scale commercialization of solid-state batteries.
“This patent approval further solidifies Sunrise’s leadership in solid-state battery anode materials,” stated Haiping Hu, Founder and CEO of Sunrise New Energy. “We are committed to increasing our R&D investment, focusing on the innovation and industrialization of next-generation battery materials, and accelerating the establishment of a globally premier new energy materials technology platform.”
