Abstract
A battery assembly includes a thermal shield. The thermal shield protects battery cells in the battery assembly from hot gases vented by a neighboring cell experiencing thermal runaway. The thermal shield acts as a one-way valve, allowing the cell experiencing thermal runaway to properly vent away hot gases, but still protecting the rest of the cells in the battery pack from the hot gases.
