Abstract
We report the synthesized mixture of MXene and NiCo LDH on nickel foam by an electrodeposition technique. The specific capacitance of the mixture attained 983.6â¯Fâ¯gâ1 at a discharge current of 2â¯Aâ¯gâ1, which is greater than that of pure MXene. Compared to NiCo LDH, the sample created through electrodeposition provided a better rate capability of 983.6â¯Fâ¯gâ1 at 2â¯Aâ¯gâ1 and 536.6â¯Fâ¯gâ1 at 50â¯Aâ¯gâ1 and cycling stability with 76% retention after 5000 cycles at 30â¯Aâ¯gâ1. 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 (36.70â¯Whâ¯kgâ1 at the power density of 1.44â¯kWâ¯kgâ1), which outperforms the other devices reported previously.
