Cell Assembly and Casing Assembly for a Power Storage Device
First Claim
1. A hybrid lead acid battery and porous carbon supercapacitor energy storage device, comprising at least one lead electrode, at least one carbon-based electrode, a separator, a casing, and an acid electrolyte;
- wherein said at least one lead electrode comprises an active lead-based mass applied to a lead-based current collector, and a low conductivity sheet of porous material which envelops said lead based mass and said lead-based current collector so as to insulate the same and so as to permit passage of electrolyte and lead-based ions therethrough;
wherein said at least one carbon-based electrode comprises a sheet of highly conductive material sealed between two sheets of electrically conductive shield material which is chemically resistant to said acid electrolyte, and highly porous carbon in electrical contact with said sheet of highly conductive material; and
wherein said casing is such as to apply and maintain compression forces against the faces of said at least one lead electrode and said at least two carbon-based electrodes, when assembled, and to provide a void space in the interior of an assembled energy storage device.

Abstract
A hybrid lead acid battery and porous carbon supercapacitor energy storage device is asymmetrically supercapacitive and comprises at least one lead electrode, at least two carbon-based electrodes, a separator, a casing, and an acid electrolyte. The lead electrode has a non-conductive sheet of porous material which envelops a lead based mass and lead-based current collector. Each carbon-based electrode is moderately conductive, having a sheet of highly conductive material between two sheets of electrically conductive shield material, and highly porous carbon adhered to the highly conductive material. The casing applies and maintains compression forces against the faces of the electrodes, and provides a void space in the interior of an assembled energy storage device.
