<p>Chromogenic materials have garnered significant attention due to their multifunctional attributes and potential to enhance energy-efficient systems, including smart windows, chromic sensors, and advanced optoelectronic applications. Developing redox-active chromic materials with diverse color states, high stability, pronounced contrast, and low-voltage operation remains a critical challenge, necessitating innovative strategies to optimize properties for electrochemical performance. In this study, irregularly oriented rod-shaped vanadium pentoxide thin films were synthesized via thermal evaporation, serving as the chromic layer with remarkable color contrast properties. This study delivers a comprehensive comparative analysis of the structural and optical properties of the chromic material by employing advanced characterization techniques, including XRD, FE-SEM, SEM, FT-IR, and Raman spectroscopy, to elucidate the intrinsic attributes of bulk V₂O₅ and V₂O₅ thin films. Cyclic voltammetric study elucidates that V₂O₅ exhibits dual functionality as both anodic and cathodic coloration, facilitated by the reversible insertion of Li⁺ ions via a diffusion-controlled mechanism. Chronoamperometry reveals an impressive contrast ratio with ΔT value of 30.13% at a wavelength of 436&#xa0;nm, exceptional cycling stability, and a swift response time less than 4&#xa0;s, attributes that are pivotal for enhancing coloration efficiency when paired with an optimized counter electrode. The findings from this study provide a fundamental understanding that can inspire advancements in the design and fabrication of high-performance electrochromic devices, emphasizing the role of chromic layer optimization in achieving superior device efficiency and durability.</p>
