Abstract:
1. A supercapacitor comprising: a first electrode substrate having a surface coated with an active material; a second electrode substrate having a surface coated with the active material, wherein the first electrode substrate has a polarity reverse to that of the second electrode substrate; a series connection electrode substrate having a surface coated with the active material, wherein the first and second electrode substrates are arranged horizontally and stacked with the series connection electrode substrate; a first middle electrode substrate having top and bottom surfaces coated with the active material and stacked between the first electrode substrate and the series connection electrode substrate; and a second middle electrode substrate having top and bottom surfaces coated with the active material and stacked between the second electrode substrate and the series connection electrode substrate, wherein the first electrode substrates, the first middle electrode substrate and the series connection electrode substrate include stacking portions each having opposite surfaces arranged with a frame-shaped insulating ring, wherein the electrolyte is accommodated in spaces enclosed by the opposite surfaces of each stacking portion of the first electrode substrates, the first middle electrode substrate and the series connection electrode substrate and each insulating ring, wherein the second electrode substrates, the second middle electrode substrate and the series connection electrode substrate include stacking portions each having opposite surfaces arranged with a frame-shaped insulating ring, wherein the electrolyte is accommodated in spaces enclosed by the opposite surfaces of each stacking portion of the second electrode substrates, the second middle electrode substrate and the series connection electrode substrate and each insulating ring, wherein the first and second electrode substrates and the first and second middle electrode substrates each has a surface area equal to a half of a surface area of the series connection electrode substrate.
