(US6068947-A)   NOVELTY - The batteries are bonded together in series in a stack on a substrate with a conductive adhesive electrically connecting their peripheral edges. The construction minimizes the volume taken up by the battery stack. The batteries may also be connected in parallel.    USE - Thin profile battery stacks.    ADVANTAGE - The construction minimizes the volume taken up by the battery stack.
