We present a detailed study of dynamical, structural and electrical properties of a sulfonium-based ionic liquid and its mixtures with acetonitrile as electrolytes for supercapacitors by means of molecular dynamics simulations. The calculated viscosity and ionic conductivity are in excellent accordance with experimental data. The addition of acetonitrile decreases viscosity (increases ionic conductivity), that affects the charging time of the supercapacitors (increase power performance) without losing the capacitance performance (energy performance).
