DOVER, USA, Dec. 08, 2025 — Sunrise New Energy Co., Ltd. (NASDAQ: EPOW) (“Sunrise” or the “Company”) disclosed that its invention patent entitled “High-Capacity Alloy Anode Material for Lithium-Ion Batteries and Its Preparation Method” (Patent No. CN2025105491347) has been formally published. This patent centers on the structural design and preparation methods for next-generation high-capacity alloy anode materials, intended for deployment in solid-state battery anodes. The future development of this innovation is anticipated to drive the progressive evolution of high-capacity alloy anode technologies.
Relative to conventional graphite anodes, alloy-based anode materials employ alloying reactions for lithium storage, delivering substantially higher theoretical capacities and increased potential for boosting energy density. Nevertheless, these materials commonly encounter challenges such as volume expansion, structural instability, and diminished cycling durability during repeated lithiation and delithiation cycles. These issues are exacerbated in solid-state battery systems, which must accommodate elevated pressure, denser electrode structures, and more stringent interfacial stability demands.
This innovation improves both capacity and cycling performance. When deployed in solid-state battery applications, materials with these characteristics can potentially create more stable interfaces with solid electrolytes, minimize interfacial impedance growth, and facilitate the development of high-energy-density, fast-charging solid-state battery systems.
Sunrise noted that the issuance of this patent marks another milestone in the Company’s technical roadmap for next-generation solid-state battery anode materials. Sunrise seeks to build a more comprehensive solid-state anode materials platform and further reinforce its leadership in advanced battery materials.
