Abstract

The development of high-energy electrodes for supercapacitors has been thoroughly explored for use in electronics and technological applications. In this research, we synthesized a Ti3C2Tx-Cr2O3 composite through an etching process followed by a hydrothermal method. Cyclic voltammetry (CV) results showed that the Ti3 C2Tx-Cr2O3 nanocomposite (NC) achieved a high specific capacity of 315 C/g at a sweep rate of about 10 mV/s. The electrochemical impedance spectroscopy (EIS) study revealed that the Ti3C2Tx-Cr2O3NC had solution impedance (Rs) and charge transport impedance (Rct) values of 0.8 Ω and 1.3 Ω, correspondingly. The galvanostatic charge and discharge (GCD) tests confirmed long charge and discharge times and excellent rate capability for the Ti3C2Tx-Cr2O3NC, with a specific capacity of approximately 622 C/g. Additionally, cyclic stability tests indicated that the Ti3C2Tx-Cr2O3NC retained 90.6% of its capacitive performance even after 3000 cycles.
