Abstract

A single cell for a battery includes electrodes, preferably electrode foils, which are arranged within a cell housing. A current output lug is electrically connected to each electrode, and at least electrodes of opposite polarity are separated and electrically insulated from one another by a separator, preferably a separator foil. Current output lugs having the same polarity are electrically conductively connected to a pole, wherein the respective poles are guided from the interior of the cell housing to the outside. Each pole is electrically conductively connected to an electrically conductive area on an outer side of the cell housing, wherein the relevant two areas of different polarity are electrically insulated from one another. The pole lugs which are arranged on the relevant areas project in a free-standing manner out of the cell housing.
