초록

2019년부터 건조 중인 장보고-III Batch-II급 잠수함은 축전지로 리튬이온전지를 탑재할 예정이다. 리튬이온전지는 다른 2차 전지에 비해서 에너지 밀도와 기전력이 높고 충·방전이 쉬운 장점이 있지만, 물리적 손상이나 온도 상승, 화학적 결함에 따른 열 폭주 (thermal runaway) 현상으로 인한 폭발 및 화재 위험성을 내재하고 있다. 따라서 해상에서 단독으로 활동하는 잠수함에서 대량의 리튬전지를 운용하기 위해서는 효과적인 화재 안전장치를 필요로 한다. 본 연구는 이러한 측면에서 대량의 리튬이온전지를 잠수함이라는 특수하고 한정된 공간에서 안정적으로 운용할 수 있도록 화재 발생 시에도 완벽하게 통제 가능한 모듈단위 소화장치의 개발 현황 및 실증 결과를 소개한다.

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.
