Abstract
A flexible charge storage device in the form a supercapacitor includes a flexible capacitive element, which is housed within a flexible package. The capacitive element includes a plurality of interleaved sheet electrodes which have an insulator or separator between them and which are stacked in a face-to-face configuration. Alternate electrodes are interconnected by way of respective opposed tabs that extend outwardly from the capacitive element. The supercapacitor also includes a first terminal and a second terminal that are respectively electrically connected with the opposed tabs. The flexible package includes a single folded sheet. Ends of the package, as well as the portions of both sides, which overlap, are fixedly and sealingly abutted against one another by way of heat welding or the like. Accordingly, an electrolyte is retained within the package.
