Abstract

A cell for an electrical energy store is provided, including a cell housing within which there is arranged an electrode and on the outer side of which there is arranged a terminal which is galvanically connected to the electrode, wherein an electrical securing element is connected in a current path between the terminal and the electrode for the purposes of galvanic separation of the electrode and of the terminal. The cell is characterized by having the securing element arranged outside the cell housing. In this way, it is possible in a simple manner for the state of charge of the cell to be checked, and also for the cell to be discharged, from the outside.
