1. A method for monitoring a temperature of a battery, the method comprising:

  • disposing a battery having a first cell and a second cell within a container;

    applying a first thermochromatic coating to the first cell;

    applying a second thermochromatic coating to the second cell;

    applying a third thermochromatic coating to the battery;

    applying a fourth thermochromatic coating to the container;

    directing electromagnetic radiation towards the first thermochromatic coating, the second thermochromatic coating, the third thermochromatic coating, and the fourth thermochromatic coating;

    observing a thermochromatic response emitted by the first thermochromatic coating, the second thermochromatic coating, the third thermochromatic coating, and the fourth thermochromatic coating; and

    identifying at least one portion of the battery that has experienced temperatures exceeding a predefined threshold temperature and amount of time at temperatures exceeding the predefined threshold temperature based on the thermochromatic response.
