Title:
SYSTEMS FOR SUPPRESSING ADVERSE EXOTHERMIC REACTIONS IN ENERGY STORAGE CONTAINERS
Document Type and Number:
Japanese Patent JP2022160365
Kind Code:
A
Abstract:
To solve the problem in present methodologies for aircraft protection that are insufficient in suppressing thermal runaway events in high-energy density batteries such as lithium-ion cells.SOLUTION: Systems are for suppressing adverse exothermic reactions in energy storage containers. One energy storage system includes: a container configured to support a plurality of battery cells; a plurality of battery cells disposed inside and supported by the container; an agent supply port attached to the container; and a tube disposed inside the container and having a closed end and an open end. The open end of the tube is in fluid communication with the agent supply port. The tube comprises fusible portions which are designed to melt or soften at a temperature lower than a melting or softening temperature of another portion of the tube. In response to the melting or softening of the fusible portions of the tube, pressurized exothermic reaction-suppressing agent is supplied into the container via the tube.SELECTED DRAWING: Figure 1
