Abstract
A battery is disclosed having a frame with conducting parts which are separated by insulating parts to form a cavity. The battery includes a cell located in the cavity having electrodes connected to the conducting parts. An insulating cover foil covers the cell. The conducting parts extend substantially along two sides of the frame. In addition, an insulating foil is located over inner surfaces of the conducting parts, where the inner surfaces face toward the cavity. Instead a single cell, many cells may be provided in the cavity, where the cells are vertically stacked over one another connected either in parallel or in series.
