Energy storage structures and fabrication methods thereof
First Claim
1. A method comprising:
- fabricating a pouchless supercapacitor structure, the fabricating comprising;
providing a first conductive sheet portion and a second conductive sheet portion separated by a permeable separator sheet, the first conductive sheet portion and the second conductive sheet portion each defining, at least in part, a respective outer wall of the supercapacitor structure;
providing a first electrode at a first surface region of the first conductive sheet portion, the first electrode facing a first surface of the permeable separator sheet and providing a second electrode at a second surface region of the second conductive sheet portion, the second electrode facing a second surface of the permeable separator sheet, the first surface and the second surface of the permeable separator sheet being opposite surfaces thereof;
providing at least one border between the first conductive sheet portion and the second conductive sheet portion, the at least one border encircling and forming a bordering frame around at least one of the first electrode or the second electrode, wherein the bordering frame facilitates forming an electrolyte receiving chamber extending through the permeable separator sheet, the electrolyte receiving chamber being defined, at least in part, by the first conductive sheet portion, the second conductive sheet portion and the at least one border; and
providing an electrolyte within the electrolyte receiving chamber, including in contact with the first electrode and the second electrode, wherein the electrolyte is capable of passing through the permeable separator sheet, and wherein the electrolyte is provided through a port insert through a border of the at least one border of the pouchless supercapacitor structure.

Abstract
Energy storage structures and fabrication methods are provided. The method include: providing first and second conductive sheet portions separated by a permeable separator sheet, and defining, at least in part, outer walls of the energy storage structure, the first and second surface regions of the first and second conductive sheet portions including first and second electrodes facing first and second (opposite) surfaces of the permeable separator sheet; forming an electrolyte receiving chamber, defined, at least in part, by the first and second surface regions, including: bonding the first and second conductive sheet portions, and the permeable separator sheet together with at least one bonding border forming a bordering frame around at least a portion of the first and second electrodes; and providing an electrolyte within the electrolyte receiving chamber, including in contact with the first and second electrodes, with the electrolyte being capable of passing through the permeable separator sheet.
