Negative thermal expansion current interrupter

Abstract

An electric power system such as, for example, a circuit, an electric appliance, an electric generator, and/or an energy storage system, can be coupled with a negative thermal expansion component. The negative thermal expansion component can be formed from a material having negative thermal expansion properties such that the negative thermal expansion component contracts in response to an increase in temperature. The contraction of the negative thermal expansion component can form a nonconductive gap that disrupts current flow through the electric power system. The disruption of the current flow can eliminate hazards associated with the electric power system overcharging, overheating, and/or developing an internal short circuit.
