Description

Module including fire extinguishing liquid-integrated cover The present invention relates to a module comprising a cover with a built-in digestive fluid. Referring to Korean Patent Publication No. 10-2024-0100233 and others, conventional battery modules generally use a method of inserting fire extinguishing panels inside the module to ensure safety in the event of a fire. These fire extinguishing panels are placed between battery cells to prevent the spread of fire and suppress initial fires. This technology contributes to enhancing the safety of battery modules and plays an important role, particularly in devices using high-energy-density batteries such as electric vehicles. However, the method of inserting these fire suppression panels inside the module causes several problems. The biggest issue is that the panels occupy a significant amount of space within the battery module. Battery modules must contain as many battery cells as possible within a limited space, but the insertion of fire suppression panels restricts the placement of battery cells, resulting in a decrease in the battery module's energy density. Furthermore, the insertion of fire extinguishing panels increases complexity in the design and manufacturing processes of battery modules. Additional design considerations are required for the proper placement of the panels, which can lead to increased manufacturing costs. Therefore, at the current level of technology, while the method of inserting fire extinguishing panels may be effective in providing safety, it has limitations in terms of space efficiency and energy density.
