☈ Super Capacitor Vs Car Battery ☈
Unlike ordinary capacitors, batteries store energy in a chemical reaction. And because of this the ions are actually inserted into the atomic structure of an electrode. Unlike in an capacitor, the ions simply "cling". This is important because storing energy without chemical reactions allows super capacitors to charge up and discharge much, much faster than batteries. And because capacitors does not suffer the wear caused by chemical reactions, they also last a lot longer. Normally if we drain our car battery to much and try to start our car it will cause more damage to the car battery and eventualy it will not charge back up to it's maximum again. However this is not true for super capacitors. For example a capacitor the size of a D-cell battery, has a capacitance of about 20 microfarads. But if we take a similarly sized supercapacitor, it has a capacitance of 300 Farads. What this means is at the same voltage, the supercapacitor could in theory store up to 15
