First Claim
1. A dry preunit for an energy storage device comprising:
- at least a first cell for storing energy, said first cell comprising, in combination;
a. a first electrically conductive electrode;
b. a second electrically conductive electrode, said first and second electrodes being spaced apart by a first predetermined distance;
c. first dielectric gasket means interposed between said first and second electrodes, for separating and electrically insulating said first and second electrodes;
d. a first high surface area electrically conducting coating layer formed on one surface of said first electrode, such that said first coating layer is interposed between said first electrode and said gasket means; and
e. a plurality of protrusions on said first coating layer,whereby, when said first electrode, said second electrode and said first gasket means having a centrally located opening are bonded together to form said first cell, an air filled fill gap is formed therebetween.

Abstract
A dry preunit (10), includes a plurality of cells (110, 112, 114) in a true bipolar configuration, which are stacked and bonded together, to impart to the device an integral and unitary construction. Each cell (114) includes two electrically conductive electrodes (111A, 111B) that are spaced apart by a predetermined distance. The cell (114) also includes two identical dielectric gaskets (121, 123) that are interposed, in registration with each other, between the electrodes (111A, 111B), for separating and electrically insulating these electrodes. When the electrodes (111A, 111B), and the gaskets (121, 123) are bonded together, at least one fill gap (130) is formed for each cell. Each cell (114) also includes a porous and conductive coating layer (119, 120) that is formed on one surface of each electrode. The coating layer (119) includes a set of closely spaced-apart peripheral microprotrusions (125), and a set of distally spaced-apart central microprotrusions (127). These microprotrusions (125, 127) impart structural support to the cells, and provide additional insulation between the electrodes. An energy storage device (10A) such as a capacitor, is created with the addition of an electrolyte to the gap (130) of the dry preunit (10) and subsequent sealing of the fill ports.
