manner, mounted the electrodes side-by-side, similar to the fingers that crossed each other. This helps to expand the usable surface area of two electrodes and reduces the route that ions in the electrolyte need to propagate. The new supercapacitors are therefore equipped with higher charging and speed performance than stacked contrast objects. People can even make this stuff at home, researchers say. Richard Kana said that for supercapacitors, it is "fast" is only a number of upgrades, "small
