Transition metal sulfides have become famous in high energy density supercapacitor materials owing to their rich redox and conductivity. While development has achieved a breakthrough terms of capacitance, there is little knowledge from the theoretical perspective on how dopants play role enhancing capacitances. In this work, pseudocapacitance quantum capacitance were evaluated through first-principles calculation describe transition sulfide, which here represented by copper sulfide (CuS). The resulting (
