Abstract
Transition metal nitrides are highly stable and electrochemically efficient, making them a promising material for supercapacitor electrodes. Herein, for assessing the synergistic effects of metal-organic framework via transition metal nitrides, we synthesized chromium nitride electrode using magnetron sputtering followed by the deposition of copper-trimesic acid. Electrochemical testing in half and full cell configurations reveals that chromium nitride/copper-trimesic acid has the lowest charge transfer resistance, indicating its quick charge transport pathways, leading to an increased specific capacity (1651C/g at 1.5 A/g) and notable rate capability. Persuaded by the exceptional capacitive and charge storage potential, a two-cell mode-based hybrid supercapacitor was fabricated using activated carbon and chromium nitride/copper-trimesic acid. This combination demonstrated the highest energy density of 94.5 Wh/kg, maximum power density of 7750 W/kg while functioning at 1.6 V with cycling stability of 97.9 % after 3000 galvanostatic charge discharge cycles. Additionally, for examining the diffusive and capacitive behaviors of devices, two different semi-empirical models were further used and compared, which shed light on the special characteristics and implementation of supercapattery device.
