The energy stored (E) in a capacitor and the rate at which it delivers the energy (i.e., charge/discharge rates; power density) are important performance metrics; the energy is expressed as a function of both the capacitance (C) and the cell voltage (V) (Equation (1)) [40,45].
Therefore, in order to integrate both high power density and high energy density into the same device, researchers have developed a new energy storage device, lithium-ion capacitors (LICs) [5].
