Abstract

The invention provides an EC bundle having a plurality of cells. In turn, each cell respectively comprises: a pair of sheet-like electrodes; electrolyte interposed between the electrodes; and a sheet like current collecting element. The sheet-like current collecting element, which includes a pair of generally opposite main faces, projects from at least one of the sheet-like electrodes and is electrically connected thereto. Moreover, the plurality of cells are arranged into a stack such that their respective sheet-like current collecting elements are in a side-by-side relationship with their main faces generally facing one another. The EC bundle further comprises a current collecting terminal featuring a pair of arms in a spaced apart relationship which define a recess which receives the sheet-like current collecting elements and which establishes an electrical connection with them. The arms of the current collecting terminal overlap at least a portion of a main face of one of the sheet-like current collecting elements.
