    Abstract: In a capacitor using a capacitor element having an anode foil and a cathode foil wound with a separator interposed between the anode foil and the cathode foil, the separator includes a low insulation part having a low insulation function between the anode foil and the cathode foil, and the low insulation part may be included within a range of 90 % in a central portion in a height direction of the capacitor element and within a range of 5 to 90 % in a diametrical direction from the center of the capacitor element. As a result, when the capacitor falls into an abnormal state, a damage of a case or a sealing plate can be avoided, and abnormal situations such as the capacitor element protruding out of the case can be avoided.

    Abstract: A short-circuit device for an electrochemical device includes: a first electrical conductor; a second electrical conductor; a porous conductive layer positioned between the first electrical conductor and the second electrical conductor; and an insulating layer positioned either or both of between the porous conductive layer and the first electrical conductor and between the porous conductive layer and the second electrical conductor. The insulating layer contains a thermoplastic resin and has an area density of more than 0.15 mg/cm 2 , and when this area density is taken to be Ma and the area density of the porous conductive layer is taken to be Mb, a relationship formula: 0.15 ≤ Ma/Mb ≤ 2.40 is satisfied.

    Abstract: A capacitor assembly (1) comprises a number of serially connected capacitor element groups (2), each of which comprises a plurality of capacitor elements (12, 14) connected in parallel. The capacitor assembly is to allow an operation which is as long as possible even in the event of individual capacitor elements failing while minimizing the risk of an explosion of the capacitor assembly. For this purpose, the capacitor elements (12, 14) of at least one of the capacitor element groups (2) comprise a first sub-quantity and a second sub-quantity of capacitor elements (12, 14).The capacitor elements (14) of the first sub-quantity have a fuse (18), and the capacitor elements (12) of the second sub-quantity do not have a fuse (18). The basis of the invention is that an operation which is as long as possible can be achieved even in the event of individual malfunctioning capacitor elements of a capacitor element group in that, wherever possible, capacitor elements with fuses are used which separate the corresponding capacitor element in the event of a failure and do not generate a substantial change in the capacitance of the entire capacitor assembly. However, in order to prevent an avalanche effect in which the entire capacitor element group is separated, a sub-quantity of the capacitor elements, i.e. in particular at least one of the capacitor elements in the capacitor element group, is also to be designed without a fuse such that a capacitor element is always provided which generates a bridge of the respective capacitor element group in the event of a failure. In this manner, a bridge of the capacitor element group is always achieved during an avalanche effect in which all of the fuses are opened.
