Supercapacitor vs Battery
While they can''t store as much energy as a comparably sized lithium-ion battery (they store roughly ¼ the energy by weight), supercapacitors can compensate for that with the speed of charge. In some cases, they''re nearly 1,000x faster than the charge time for a similar-capacity battery.
