Abstract

An energy storage device is provided including multiple back-to-back-disposed storage cells, from the first end of which the plus pole is made to emerge and from the other end of which the minus pole is made to emerge, thereby creating a series circuit of the storage cells. In order to reduce fabrication costs, it is proposed that each of the storage cells have a continuous opening between the plus pole and the minus pole, through which opening a guide rod extends that secures the back-to-back-disposed storage cells in this position.
