Description
As the globe moves toward sustainable energy options, effectively storing and managing energy becomes increasingly crucial. Advanced energy storage technologies can bridge the gap between energy generation and consumption, ensuring a reliable and stable supply even when renewable sources are intermittent. In this context, the rise of two-dimensional layered Ti3C2 MXene as a promising electrode for supercapacitors is particularly noteworthy, owing to its unique physical, chemical, and electrocatalytic attributes. Despite its potential, the immediate collapse and aggregation of MXene layers pose significant obstacles to their widespread usage in energy storage applications. This study explores advanced energy storage technologies using V3S4 coupled Ti3C2 MXene as electrodes in asymmetric supercapacitors. By combining the unique properties of V3S4 and Ti3C2 MXene, new avenues for improving the performance of supercapacitors are being unlocked. The experimental results indicate that the Ti3C2/V3S4 electrode exhibits an enhanced specific capacitance (Csp) of 1323.7 Fg-1 at a current density of 1 Ag-1, with an outstanding capacitance retention of 90.5 % after 2000 cycles. An assembled asymmetric supercapacitor, Ti3C2/V3S4//activated carbon shows superior energy storage efficiency, achieving a Csp of 258.4 Fg-1 at 2 Ag-1. The device exhibits a high energy density of 60.6 Whkg?1 at a power density of 649.2 Wkg-1, while holding onto a capacitance retention rate of 91.1 % over 10,000 cycles. 2025 Elsevier Ltd
