Embodiments disclosed herein may be generated related to the prevention of a thermal catastrophic event within a battery cell. A thermal catastrophic event may be caused by many issues associated with a battery cell such as an internal short within the battery cell. To prevent a thermal catastrophic event an apparatus that may include a battery cell and a phase change material in contact with one or more portions of the battery cell. The phase change material may be configured to change phases at a temperature that is close to that of a thermal runaway event. The phase change material may further have a high heat of fusion such that the phase change material may absorb heat within a battery cell in the case of thermal runaway event in order to prevent a thermal catastrophic event within the battery cell.
