AbstractWe report the synthesized mixture of MXene and Ni–Co LDH on nickel foam by an electrodeposition technique. The specific capacitance of the mixture attained 983.6 F g at a discharge current of 2 A g, which is greater than that of pure MXene. Compared to Ni–Co LDH, the sample created through electrodeposition provided a better rate capability of 983.6 F g at 2 A g and 536.6 F g at 50 A g and cycling stability with 76% retention after 5000 cycles at 30 A g. Moreover, a solid-state asymmetric supercapacitor with MXene-LDH as the positive electrode and multi-walled carbon nanotube coated on the nickel foam as the negative electrode delivers high energy density (36.70 Wh kg at the power density of 1.44 kW kg), which outperforms the other devices reported previously.
