Transition-metal trichalcogenides, distinguished by their quasi-one-dimensional (quasi-1D) structures, hold substantial potential for advanced technologies, yet their supercapacitive behavior remains largely unexplored. Here, solution-exfoliated zirconium trisulfide (ZrS3) nanoribbons are introduced as a high-performance electrode material for supercapacitors. Density functional theory analysis reveals that quasi-1D ZrS3 possesses a significant density of states near the band edges, giving rise to intrinsically high quantum capacitance as an electronic property. Solution-based exfoliation enables efficient production of ZrS3 nanoribbons from bulk microparticles, yielding a quasi-1D structure with considerably increased surface area. In electrochemical measurements, the combination of the quasi-1D structure and large quantum capacitance allows the exfoliated ZrS3 nanoribbons to achieve a high specific capacitance of 284 F g–1, exceeding that of the bulk microparticles by more than 40-fold. These results demonstrate that solution-based dimensional engineering enhances interfacial charge storage, while the intrinsically high quantum capacitance supports efficient electronic charge accommodation, highlighting ZrS3 nanoribbons as promising supercapacitor electrode materials.
