Supercapacitors: Review of materials and fabrication methods

A supercapacitor differs from other types of capacitors due to its large surface area and thin dielectric layer between the electrodes. As a result, their capacitances are much higher than those of regular capacitors [3] percapacitors have a much higher energy storage capacity when used in conjunction with other energy storage technologies like fuel cells or …
