ELECTRIC ENERGY STORAGE DEVICE ELECTRODE INCLUDING AN OVERCURRENT PROTECTOR
First Claim
1. An apparatus, comprising:
- a capacitor case sealed to retain electrolyte;
at least one electrode disposed in the capacitor case, the at least one electrode comprising an overcurrent protector formed from a portion of the electrode;
a conductor coupled to the overcurrent protector and in electrical communication with a remainder of the electrode, the conductor sealingly extending through the capacitor case to a terminal disposed on an exterior of the capacitor case;
a second electrode disposed in the capacitor case;
a separator disposed between the electrode and the second electrode; and
a second terminal disposed on the exterior of the capacitor case and in electrical communication with the second electrode, with the terminal and the second terminal electrically isolated from one another,wherein the overcurrent protector is to interrupt electrical communication between the terminal and the remainder of the electrode at a selected current level.
