In an electrochemical energy store or energy converter having an electrochemically active material in a package (1) or in a housing (1) which is composed of electrochemically inactive material, a wall (2) of the package or of the housing or a device (3) of the energy store or energy converter, which device is fitted or arranged in, at or on a wall of the package or of the housing, has a sealing material (4) at least at points, the specific volume of said sealing material increasing when a threshold temperature is exceeded. The sealing material can be arranged in, at or on the wall of the package or of the housing in such a way that the increase in the specific volume of the sealing material which occurs when the threshold temperature is exceeded can contribute to sealing off a leak (5) in the package or in the housing or to closing an opening (6) in a device of the energy store or energy converter. |
