Abstract:
A package for a power storage device includes a metal foil layer, an insulation layer laminated on at least center portion of one surface of the metal foil layer, and a heat-sealable resin layer arranged one surface of the metal foil layer or a region corresponding to a periphery of the one surface of the metal foil layer. With this, thinning, weight saving, and shortening of the production time can be attained.

Abstract:
Electrochemical energy storage devices such as electric double layer capacitors include flexible metal contact current collectors establishing electrical contact with a conductive housing and a conductive cover. The flexible current collector simplifies manufacturing of the device and avoids laser welding on the conductive housing. The manufacture devices are operable with a reduced direct current resistance by virtue of the flexible current collector.

Abstract:
The invention relates to an assembly for storing electrical energy (1), comprising: an envelope comprising a body (10) having at least one side wall (11) and at least one open end, and at least one cover (20) for closing the at least one open end of the body; at least one energy storage element (50) arranged inside the envelope; and an electrolyte solution also inside the envelope. The invention is characterised in that the storage assembly also comprises: a pressure-increasing accelerator (40) for generating an overpressure inside the assembly when the temperature inside the assembly is higher than a temperature threshold, especially at between 120° C. and 140° C.; and means (30) for the local fracturing of the envelope when the pressure inside the envelope is higher than a pressure threshold.
Abstract:
An electric storage device includes a container which houses an electric generating element, and a sealing plug which seals a liquid injecting hole into which an electrolyte is injected. The liquid injecting hole is provided in a bottom surface of a recessed portion provided to be recessed on one side surface of the container. The sealing plug includes an inserting portion to be inserted into the liquid injecting hole and a fitting portion to be fitted into the recessed portion. At least either a rim portion of the fitting portion or an opening rim portion of the recessed portion is provided with a plurality of plastic deformation portions. In each of n regions (n is an integer of at least 3) into which an outer circumference of the fitting portion or an inner circumference of the recessed portion is equally divided, one or more of the plastic deformation portion(s) is/are arranged, and, in each of regions into which the outer circumference of the fitting portion or the inner circumference of the recessed portion is halved with an arbitrary plastic deformation portion out of the plastic deformation portions set as a starting point, one or more of the plastic deformation portion(s) is/are arranged. An outer circumferential side surface of the fitting portion and an inner circumferential side surface of the recessed portion are welded over an entire circumference.
