A battery electrode assembly includes a current collector with conduction barrier regions having a conductive state in which electrical conductivity through the conduction barrier region is permitted, and a safety state in which electrical conductivity through the conduction barrier regions is reduced. The conduction barrier regions change from the conductive state to the safety state when the current collector receives a short-threatening event. An electrode material can be connected to the current collector. The conduction barrier regions can define electrical isolation subregions. A battery is also disclosed, and methods for making the electrode assembly, methods for making a battery, and methods for operating a battery.
A method of making an electrode, comprising the step of forming in a current collector a plurality of electrical isolation subregions defined at least in part by conduction barrier regions formed in the current collector, the isolation subregions having a conductive state in which the isolation subregions are not electrically isolated from other isolation subregions, and a safety state in which at least one isolation subregion is electrically isolated from at least one adjacent isolation subregion such that electrical conductivity through the adjacent isolation subregions in the safety state is reduced.
A method of operating a battery, comprising the steps of:
