N2 - The MnCo2O4.5 hexagonal nanoplates and multi-wall carbon nanotube (MWCNT)@MnCo2O4.5 composite were prepared via a rapid and low-cost co-precipitation method. The prepared materials were characterized by various characterization techniques and used as an electrode for supercapacitors. The specific capacitance values of 451 and 1292 F g−1 were obtained from MnCo2O4.5 and [email protected], respectively at 1 A g−1. Furthermore, [email protected]//AC-based device indicated the higher energy density value of 33 Wh kg−1 at the power density of 362.5 W kg−1 under the current density of 0.5 A g−1. The practical electronic application of the device was tested by powering twelve light-emitting diodes, a digital watch and a motor fan. From the results of the MnCo2O4.5 with MWCNTs, the MnCo2O4.5 is expected to be a potential viable material for high-performance electrochemical capacitors.
