Abstract:
An electrode stack assembly of an electrolytic capacitor comprising:an anode layer comprising: a first anode sheet fabricated of a valve metal having first and second sheet sides that are bounded by a first sheet edge, the first anode sheet having a first anode sheet bore extending through the valve metal from the first sheet side to the second sheet side; at least one second anode sheet fabricated of a valve metal having first and second sheet sides that are bounded by a second sheet edge, the second anode sheet having a second anode sheet bore extending through the valve metal from the first sheet side to the second sheet side; and a first malleable conductive member expansion riveted within the first and second anode sheet bores into physical and electrical contact with the valve metals of the first and second anode sheets, whereby the valve metal of the second sheet is electrically connected to the valve metal of the first anode sheet; a cathode layer; and a separator between the anode layer and the cathode layer, the separator carrying an electrolyte.
