An electrode for an energy storage device, including a substrate of at least one metal that forms a native oxide layer; and a treated layer formed on the substrate from the native oxide layer, the treated layer having a resistance that is less than the resistance of a native oxide layer. In some embodiments, the treated layer possesses at least one of the following properties: includes one or more dopants, is thinner than the native oxide layer, has a carbon coating that is applied to the treated layer which improved adhesion characteristics, and others. Further, there is an energy storage device having two or more of such electrodes, wherein the device has a low initial ESR and/or a low ESR at various intervals. Moreover, disclosed is a low resistance metal including a substrate of at least one metal that forms a native oxide layer; and a treated layer formed on the substrate from the native oxide layer, the treated layer having a resistance that is less than the resistance of a native oxide layer. Additionally, methods relating to the above devices are also disclosed.

Electrode for an energy storage device

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.
