Abstract:
TMCs have established themselves as potential electrodes for pseudocapacitors because of
their superior redox activity, short transport pathways, varied morphological, better
cyclability and numerous electrochemical active sites. FTIR, XRD, XPS, SEM, EDS, BET
and TGA were used for the characterization of prepared materials. A ternary composite
(TiO2/MOS2/SnS) electrode material was produced using a hydrothermal method. This
electrode at 1 A/g showed a high capacitance of 1519 F/g. The material maintained
impressive cyclic reliability, retaining 92.77% capacity after 10,000 (GCD) cycles. It also
displayed at 10 A/g, a coulombic efficiency of 90.4%. The energy density of 13.18 Wh/kg
and a power density of 125 W/kg were calculated. Furthermore, a full cell configuration
(two-electrode system) was constructed, achieving a capacitance of 395 F/g at 0.5 A/g. The
full cell's energy density was recorded at 79 Wh/kg, and 300 W/kg power output. This
remarkable electrochemical activity and pseudocapacitive behavior is due to synergy of its
components.
