Thin film battery with multiple individual electrochemical cells

PendingEP4723313A1Printed batteriesSmall-sized flat cells/batteries
A thin-film battery (100) with several electrochemical cells (10) is provided. The electrochemical cells (10) are mounted on a carrier film (50) as a common substrate. The electrochemical cells (10) are stacked on top of each other. Each electrochemical cell (10) is separated from an adjacent electrochemical cell by a fold edge (11) in the carrier film. The electrochemical cells (10) are electrically connected to each other by at least one conductive layer (12; 51) of the carrier film. The thin-film battery is further characterized by the fact that the carrier film has weakening lines (510) in the region of the fold edges (11).
