Synergetic Li-ion Storage Effects of Nanostructured V2O5–Modified Silicon Thin Film Anodes

Abstract

In this study, a nanostructured vanadium pentoxide (V₂O₅)-modified silicon (Si) thin film anode was successfully fabricated using radio frequency (RF) magnetron sputtering to enhance the electrochemical performance of Si-based thin film anodes for lithium-ion batteries (LIBs). Structural and morphological characterization confirmed the successful deposition of V2O5 interlayer modified Si thin film architecture with improved surface roughness and compositional uniformity. Electrochemical analyses revealed a synergistic effect between the high-capacity Si and the pseudocapacitive behavior of V₂O₅. Cyclic voltammetry (CV) and kinetic studies demonstrated a mixed charge storage mechanism, with both diffusion-controlled and capacitive contributions. The modified Si thin film anode delivered initial discharge capacity of ~2013 mAh/g, followed by a stable reversible capacity of 367 mAh/g over 180 cycles. These results suggest that V₂O₅ interlayer engineering offers a promising strategy to overcome the limitations of Si anodes and advance high-performance LIB systems.
