dc.description.abstractThis investigation presents a straightforward synthesis method for a CoWO4@Ti3C2Tx composite doped with transitional metals, serving as innovative cathode materials for supercapacitors. The study delves into the structural, morphological, and electrochemical attributes of these composites, revealing that the Ni-doped variant outperforms its Zn/Cu-doped counterparts in capacitive capabilities. Specifically, the Ni-doped MXene composite within the CoWO4 electrode exhibits a remarkable specific capacitance of 630�F�g?1 at a current density of 1�A�g?1, showcasing superior performance. Moreover, this composite demonstrates notable cycling stability, retaining 92% of its initial capacitance over 10000 cycles. To further explore practical applications, an asymmetric supercapacitor coin cell (CR2032) was assembled, when displays a high voltage window of 1.6�V in a 1�M�H2SO4 electrolyte, yielding a specific capacitance of 248�F�g?1 at 1�A�g?1. Notably, the device achieves an energy density of 63.8�Wh�kg?1 at a power density of 422�W�kg?1, accompanied by an impressive 95.6% coulombic efficiency. The practical viability of the fabricated supercapacitor prototype is underscored by its ability to power a green light-emitting diode within 10�min of a 10-s charge. This highlights the potential of the composite electrode material for constructing high-performance supercapacitors, assessed morphologically and benchmarked against other metal-doped samples. ?
