한국형잠수함 리튬전지모듈 소화장치 개발 및 실증 연구

다국어 초록 (Multilingual Abstract)

The Jang Bogo-III Batch-II class submarine, which has been under construction since 2019, is scheduled to be equipped with lithium-ion batteries as storage batteries. Lithium-ion batteries have the advantage of having higher energy density and electromotive force compared to other secondary batteries and are easy to charge and discharge, but they have the inherent risk of explosion and fire due to physical damage, temperature rise, and thermal runaway due to chemical defects. Therefore, in order to operate a large amount of lithium batteries in a submarine that operates isolated at sea, an effective fire safety device is required. In this regard, this study introduces the development status and field demonstration results of a module-based fire extinguishing device that can be completely controlled even in the event of a lithium-ion battery fire to enable stable operation of large quantities of lithium-ion batteries in Submarine.
