ELECTRODE LAMINATE AND ELECTRIC DEVICE

摘要

A film packing battery (1) comprises a plurality of cells (2) connected in series, and packing films (4, 5) for sealing them. The cell (2) is arranged such that a plurality of positive electrodes (21) and negative electrodes (24) are laid alternately in layers through separators (27). The positive electrodes (21) and negative electrodes (24) have metal foils (22, 25) coated with electrode materials (23, 26) such that the ends on either side become uncoated parts (22a, 25a). The positive and negative electrodes are laid by directing the uncoated parts (22a, 25a) to the opposite sides. Adjacent cells (2) are connected electrically while overlapping the uncoated part (22a) of the positive electrode (21) and the uncoated part (25a) of the negative electrode (24) alternately in the laying direction.
