Abstract
A high energy density rechargeable (HEDR) battery employs a combined current limiter/current interrupter to prevent thermal runaway in the event of internal discharge or other disruption of the separator. The combined current limiter/current interrupter is interior to the battery.
Claims21
-17. (canceled)
A battery, comprising:
- a current collector;
- and
- an electrode electrically coupled with the current collector, wherein the electrode is configured to cause, upon activation of at least a temperature trigger, formation of a nonconductive gap between the electrode and the current collector, wherein the formation of the nonconductive gap causes electrical decoupling of the electrode and the current collector, and wherein the electrical decoupling of the electrode and the current collector interrupts a current flow within the battery.
A method, comprising:
- forming a nonconductive gap between an electrode and a current collector within a battery, wherein the electrode and the current collector are electrically coupled, wherein the formation of the nonconductive gap is caused by the electrode in response to an activation of least a temperature trigger, wherein the formation of the nonconductive gap electrically decouples the electrode and the current collector, and wherein the electrical decoupling of the electrode and the current collector interrupts a current flow within the battery.
