The Difference Between Battery VS Supercapacitor
A supercapacitor is like a hybrid of a battery and a standard capacitor. In other words, it can hold a greater electrical charge than a standard capacitor. Not only that, but a supercapacitor can handle more frequent cycles of charging and discharging stored energy. ... Compare it to a lead-acid battery that gets no more than 1,000 charge ...
Lead-Acid Battery Basics
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.

Supercapacitors vs. Batteries: What''s the Difference?
The electrochemical process creates heat and so charging has to happen at a safe rate to prevent catastrophic battery failure. Supercapacitors can also deliver their stored power much more quickly than an electrochemical battery, for the same reason. If the battery discharges too quickly it can also lead to catastrophic failure.
