A safety device for a sealed cell () comprising alternating positive and negative electrodes respectively connected to positive and negative current output terminals () placed in a container () having an end () that is closed by a wall. The wall of the closed end presents thinning () adapted to be torn by excess pressure inside the container, and the thinning is adapted, on being torn, to interrupt electrical conduction between the electrodes of one polarity and the corresponding current output terminal. The device of the invention is simple in design, is capable of operating at low pressures, and over a wide range of pressures, and acts as a circuit interrupter without decreasing the current density that flows in the electrical circuit.

Safety device for a sealed cell

A storage cell battery unit equipped with a cooling device that uses a circulating fluid, said battery including a housing made of plastic and constituted by a case (6) and a cover (7) heat-sealed thereon, said storage cell battery being characterized by the fact that said cooling device includes two panels (12, 13) made of plastic and heat-sealed in fluid-tight manner to respective ones of two opposite walls (3, 2) of said housing, each of the panels cooperating with the corresponding wall to delimit a circulation compartment having an inlet orifice (14) and an outlet orifice (14) for said fluid at the top of the compartment.
