A supercapacitor is a modern energy storage device that can bridge the gap between batteries and conventional capacitors. The supercapacitor has advanced characteristics like higher capacitance and energy density compared to the traditional capacitor, which makes it capable to store a large amount of energy [1, 2] works on the electrostatic charge storage
The discharge and charge process cause first the expansion, then the contraction of the positive (+) active material. Expansion occurs both in the plane (height and width) of the plate as the grid is pushed/stretched by corrosion processes over time and in the thickness of the plate as the active material is forced to expand to accommodate the lead sulphate ("PbSO 4 ") with each

When a lead-acid battery is left to self-discharge (in storage or installed but seldomly used) or is exposed to excess and repeated high-rate charging (such as is the case with Start-stop vehicles), a point can be reached where the reaction at the negative plate that should convert the lead back to active material (PbSO4 back to Pb) can not accommodate all of the charging currents.
