    Supercapacitors (double-layer or ultracapacitors) are devices that store extremely large amounts of charge (from 0.022 F to 55 F) much more than a normal capacitor.  Their level of energy storage approaches around 1/10 that of a low-density battery. But, unlike a battery, the power output can be 10 times greater (a handy feature in high-current…
