The present invention provides a fire extinguishing sheet suitable for productivity, mass production, and large-scale production, wherein the fire extinguishing sheet can be used in places, facilities, structures, etc., where a fire may occur, and has an initial fire extinguishing function. The fire extinguishing sheet according to the present invention contains a fire extinguishing agent that when a predetermined temperature is reached, thermally decomposes to generate a fire extinguishing component.

An energy storage container ventilation system and an energy storage container are provided according to the present disclosure. The ventilation system includes an air conditioner, an air duct, and multiple columns of battery racks, and each battery rack includes multiple lines of battery boxes, and an air outlet of the air conditioner is communicated with the air duct, a communicating part of each battery box and the air duct is provided with a ventilation plate with the same structure or different structures. The energy storage container ventilation system of the present disclosure uses an air conditioner to dissipate heat. Ventilation plates are provided at communicating parts of the air duct and each battery box. The structure of each ventilation plate is the same or different, so as to control an air intake volume flowing into each battery box.
