Presented are thermomechanical fuses for mitigating heat propagation across electrochemical devices, methods for making and methods for using such fuses, and traction battery packs with load-bearing, sacrificial thermomechanical fuses to help prevent thermal runaway conditions. A battery assembly includes an electrically insulating battery housing with multiple battery cells disposed inside the battery housing. These battery cells are electrically interconnected, in series or parallel, and stacked in side-by-side facing relation to form adjacent, mutually parallel stacks of battery cells. Thermomechanical fuses thermally connect neighboring stacks of the battery cells. Each thermomechanical fuse is formed, in whole or in part, from a dielectric material that undergoes deterioration or deformation at a predefined critical temperature; in so doing, the thermomechanical fuse thermally disconnects a first stack of cells from a neighboring second stack of cells.

A reinforcement frame (1) for a battery pack (2) of an electric or hybrid vehicle (37), the battery pack including a plurality of battery cells lying on and secured to a shield element, the reinforcement frame including at least: a reinforcement frame fastening portion (3) provided to be secured to both the battery pack and the body of the vehicle, and a reinforcement frame hollow portion (4) provided to surround at least the battery cells.
