In this work, MXene-assisted cobalt manganese phosphate (MXene-CMP) thin films with various Co/Mn compositions were prepared on a carbon cloth (CC) substrate via an easy and efficient low-cost electrodeposition route. MXene-CMP thin films were further used as polymer-free active materials for hybrid supercapacitors. The structural, compositional, and surface properties of the prepared MXene-CMP hybrid thin films were characterized using the latest analytical methods. The H-3 electrode exhibited enhanced specific capacitance (840 F·g-1 at 2 A·g-1) with exceptional robust performance. Additionally, a symmetric H-3 MXene-CMP supercapacitor device also demonstrated a high energy density of 48 Wh·kg-1 at 1.5 kW·kg-1 power density and holds better cyclability (93% of its initial value after 5000 cycles). Finally, this work explored the strong potential of MXene-attached bimetallic phosphates for solving the electrochemical shortcomings of energy storage devices.
