Flat capacitor having staked foils and edge-connected connection members

A capacitor comprising:

• a first anode having an edge face;
• a cathode;
• a separator between the first anode and the cathode;
• and
• a connection member attached to the first anode, the connection member having a first section extending over and confronting the edge face of the first anode.

A flat capacitor comprising:

• one or more capacitor elements, each capacitor element comprising;
• an anode having a connection member attached thereto;
• a cathode;
• and
• a separator located between the anode and the cathode;
• wherein, each connection member has a front end surface substantially flush with a front end surface of a connection member or connection members adjacent to each other anode connection member, and wherein each connection member is attached to the connection member or connection members adjacent to each connection member at an edge-connection between the connection members at their substantially flush front end surfaces.

A flat capacitor comprising:

• one or more capacitor elements, each capacitor element comprising;
• an anode having a connection member attached thereto;
• a cathode;
• and
• a separator located between the anode and the cathode;
• wherein, each connection member has a surface substantially flush with a surface of a connection member or connection members adjacent to each other anode connection member, and wherein each connection member is attached to the connection member or connection members adjacent to each connection member at an edge-connection between the connection members at their substantially flush surfaces, wherein the edge-connection comprises a laser edge-weld.

A flat capacitor comprising:

• a multi-anode stack including two or more anode foils;
• a cathode;
• and
• a separator located between the anode stack and the cathode;
• wherein, each anode foil of the multi-anode stack is connected to the other foils of the multi-anode stack by a stake weld joint having a diameter less than approximately 0.060″ (1.524 mm).
