High-Quality Epitaxial N Doped Graphene on SiC with Tunable Interfacial Interactions via Electron/Ion Bridges for Stable Lithium-Ion Storage.

Abstract in brief

• The paper discusses a new method to improve lithium-ion battery anodes by growing high-quality nitrogen-doped graphene on silicon carbide (SiC), creating a heterojunction that features an intrinsic electric field and tunable interfacial interactions.
• This interface, featuring electron-ion bridges, enhances charge transfer, stabilizes the structure against pulverization, and improves overall battery performance, as confirmed by theoretical and experimental analyses.
• The resulting anode demonstrates high reversible capacity, excellent cycling stability, and superior rate capability, offering a promising strategy for advancing SiC-based anodes in lithium-ion batteries and potentially beyond.]
