Supporters from both sides took to the streets [...]
The basic principle of supercapacitors is the same as other types of electric double-layer capacitors. They all use the electric double-layer structure composed of activated carbon porous electrodes and electrolyte to obtain a large capacity. The advantages of super capacitors have the following points: 1. A farad-level capacitance in a small volume; 2. No special charging [...]
