Supercapacitors as one of the energy storage have attracted attention. The advantages of using carbon materials have so far been widely developed and researched as electrodes for supercapacitors, but their volumetric capacity is still less than optimal and less practical in long-term use. Manganese (III) oxide (Mn2O3) materials show great potential as electrodes with high theoretical specific capacitance. On the other hand, BiPO4 as an anode has added battery characteristics to get maximum results. The blending method is applied in the manufacture of composites deposited on an aluminum foil substrate. The electrochemical properties of the developed samples were studied by cyclic voltammetry (CV), Galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). The electrochemical results showed that the best electrode-specific capacitance at 20% BiPO4 percentage reached 56 Fg-1 at a current density of 1 Ag-1 with a potential window of 2 V for 50 cycles. It is hoped that these results can provide information on the potential of using the material as an optimal electrode.
