The scientific name of super capacitor is electronic double-layer capacitor. Unlike the traditional nano-dielectric capacitor with high capacitance value, the super capacitor does not use the traditional solid-state electrolyte. The energy density of super capacitors is higher than that of ordinary capacitors and smaller than that of lithium batteries. Its power density is lower than that of ordinary capacitors and larger than that of lithium batteries. Super capacitor/ultra capacitor, also known as double layer capacitor, is a new type of energy storage device, which has the characteristics of a short charging time, long service life, good temperature characteristics, energy saving and green environmental protection. The backup power supply of minute current supply for tax control computer, tax control refueling machine, vacuum switch, intelligent meter, remote meter reading system, instrument, digital camera, handheld computer, electronic door lock, program-contro...
