Abstract
A sealed accumulator (1) having an electrochemical bundle (9) including at least one positive electrode and one negative electrode arranged in a container (2); positive (6) and negative (7) current output terminals arranged on a cover (5) of the container and respectively connected to the positive and negative electrodes; a circuit-breaker including a connecting piece (10) and a membrane (20), electrically insulated from the connecting piece and suitable for deforming under the effect of an overpressure in the container, to break the connecting piece. The connecting piece extends over the top of the cover of the container and conducts an electric current between an electrode of one polarity and its current output terminal. The connecting piece is dimensioned to allow the passage of a current greater than 50 A.
