Patent Images
1. A supercapacitor, said supercapacitor comprising:
- a first plate, said first plate having a porous surface;
a second plate, said second plate having a porous surface;
a solid polymer electrolyte, said solid polymer electrolyte impregnated into the porous surface of said first and said second plate;
means for electrically connecting to said plates; and
means for housing said plates with said solid polymer electrolyte therein and said means for electrically connecting, said supercapacitor having an energy density ranging from 0.1 to 2.0 joules per cubic centimeter.

4. A process of making a supercapacitor cell, said process comprising the steps of:
-
assembling a sandwich of at least one pair of plates and a layer of solid polymer electrolyte between each pair of plates; placing said sandwich in a receiving chamber of a means for providing a high pressure shock wave to said receiving chamber; applying sufficient high pressure to cause said solid polymer electrolyte to impregnate into said plates; and removing said supercapacitor cell from said receiving chamber after applying said sufficient high pressure. - View Dependent Claims (5, 6, 7, 8)
