Abstract
An apparatus for automatically generating a fire-fighting foam at elevated temperatures is provided. The apparatus includes a container sized to hold at least one battery. Water is stored within the container. One or more cartridges made, at least in part, of a temperature-dependent breakdown material are stored within the container. The one or more cartridges contain a foaming agent. Heat generated by a failing battery causes the temperature-dependent breakdown material to fail such that the foaming agent is released from at least one cartridge to mix with the water stored within the container.
