An electric vehicle battery disconnect bracket configured disconnect one or more battery cells or modules experiencing a thermal event within a battery pack to mitigate propagation of the thermal event throughout the battery pack, including a bracket body formed of a first material on a first major surface of the body, and a second material on an opposing second major surface of the body, the first material having a larger coefficient of thermal expansion than the second material, such that an increase in temperature above a defined threshold experienced by the body causes the first material to expand more than the second material, thereby transitioning the body from a first equilibrium state representing a closed, conductive position to a second equilibrium state representing an open, isolation position.
