Abstract
A battery includes a cell casing; a first terminal; a second terminal in electrical communication with the cell casing and electrically insulated from the first terminal; an electrode assembly in the cell casing; a current interrupt device (CID) in electrical communication with the first terminal and the first electrode or with the second terminal and the second electrode; and insulation that interrupts potential electrochemical communication between the first electrode and the second terminal or between the second electrode and the first terminal. The electrode assembly includes a first electrode in electrical communication with the first terminal, a second electrode in electrical communication with the second terminal, and an electrolyte between the first and second electrodes. The insulation interrupts potential electrochemical communication between the first electrode and the second terminal or between the second electrode and the first terminal when under a charging or overcharging condition and when the CID is activated, thereby interrupting the electrical communication between the first terminal and the first electrode or between the second terminal and the second electrode.
