Fluorinated Graphdiyne‐Modified Graphite: Boosting Ion Diffusion for Advanced Lithium‐Ion Battery Anodes
Year: 2026
Type: article
Abstract: Although graphite is widely used as the primary anode material in commercial lithium-ion batteries, it suffers from inherent limitations in specific capacity, rate capability, and long-term cycling stability. To overcome these challenges, this study successfully introduced fluorinated graphdiyne into graphite anodes via a simple and cost-effective physical mixing approach. These findings indicate that fluorinated graphdiyne modified graphite (F-G) effectively reduce the energy barrier for lithium ions migration, enhance ion diffusion within graphite electrodes, significantly reduce interfacial impedance, and suppress harmful side reactions. As a result, the cycle durability of the battery is improved. This work provides theoretical insights into the regulatory mechanism of modification on the electrochemical performance of graphite anodes, offering a new perspective for the design of high-performance lithium-ion battery materials, with certain scientific and practical significance.
