Abstract Electrolytic capacitor cells of paste electrode type are formed integrally in a composite or laminated belt in a predetermined pattern and subsequently severed or otherwise separated therefrom to provide a plurality of individual cells or stacked cell sets of desired shape. The belt includes at least one inner sheet of ion conducting/electron insulating material, outer sheets of electron conducting material, and intermediate sheets of insulating gasket material respectively interposed between the inner sheet and respective outer sheets. Each intermediate sheet has a plurality of holes arranged in a predetermined pattern and aligned with the holes in the other intermediate sheet for accommodating respective electrodes of a like number of pairs which have opposite surfaces in operative contact with the inner and respective outer sheets. The belt is either continuously formed or formed in discrete lengths, and adjacent sheets thereof are either adhesively bonded as by double-sided adhesive tape or bonded by covulcanization.
An apparatus for manufacturing electrical storage cells of the type including a pair of opposed electrodes, a separator between and in operative contact with inner surfaces of the electrodes, a pair of electrode connectors respectively in operative contact with outer surfaces of the electrodes, and a pair of gaskets respectively confining the electrodes between the separator and respective electrode connectors, said apparatus comprising means for longitudinally advancing and assembling together an inner sheet of separator material, outer sheets of connector material at opposite sides of the inner sheet, intermediate sheets of gasket material between the inner sheet and respective outer sheets with holes in each intermediate sheet aligned with respective holes in the other intermediate sheet and spanned at opposite ends by the inner sheet and respective outer sheet, to form a composite belt including a plurality of such cells intergrally in such belt; means for positioning electrodes at such holes in one intermediate sheet and other electrodes at such holes in the other intermediate sheet prior to assembling of the inner and respective outer sheets at opposite sides of the respective intermediate sheet; and means for separating the individual cells from the composite belt.
