Fire suppression for energy storage devices

An energy storage device container for suppressing fires, the energy storage device container comprising:

• a compartment comprising a compartment material, the compartment being configured to receive an energy storage device;
• a chamber configured to hold a fire suppressive agent, the chamber being positioned above the compartment;
• and
• a barrier comprising a barrier material, the barrier being disposed between the compartment and the chamber and configured to physically separate the chamber from the compartment to inhibit the fire suppressive agent from entering the compartment when the barrier is in a first physical state,
• wherein the barrier is configured to change from the first physical state to a second physical state in response to thermal energy having a threshold temperature to allow the fire suppressive agent to enter the compartment to contact the energy storage device,
• wherein the barrier is separated from the energy storage device by a distance without another material positioned between the barrier and the energy storage device to allow the fire suppressive agent to dissipate as it travels across the distance and contact a greater portion of the energy storage device,
• wherein an ignition temperature of the barrier material is less than an ignition temperature of compartment material, and
• wherein the threshold temperature is less than the ignition temperature of the compartment material.

A container for holding an energy storage device, the container comprising:

• a compartment configured to receive an energy storage device;
• a chamber configured to hold a fire suppressive agent, the chamber being positioned above the compartment;
• and
• a barrier disposed between the compartment and the chamber, the barrier being configured to physically separate the chamber from the compartment to inhibit the fire suppressive agent from entering the compartment,
• wherein a structure of the barrier is configured to change responsive to thermal energy to allow the fire suppressive agent to enter the compartment,
• wherein a structure of the compartment is more resistant to change, responsive to the thermal energy, than the structure of the barrier, and
• wherein the barrier is separated from the energy storage device by a distance without another material positioned between the barrier and the energy storage device to allow the fire suppressive agent to dissipate as it travels across the distance and contact a greater portion of the energy storage device.
