High voltage capacitors wikipedia.
A supercapacitor sc also called an ultracapacitor is a high capacity capacitor with a capacitance value much higher than other capacitors but with lower voltage limits that bridges the gap between electrolytic capacitors and rechargeable batteries it typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors can accept and deliver charge much.
