초록

본 연구는 잠수함용 리튬 이온 배터리(LIB)의 기본 개념과 열폭주 메커니즘 및 해상 사고 사례를 분석하고, 열폭주 개선 연구와 안정성 설계 현황을 조사하였다. 잠수함용 LIB는 다층 안전장치를 도입하여 설계되었으며, 엄격한 검증시험을 통해 모든 안전성 기준을 충족하고 있다. 우리나라의 LIB 및 ESS 기술은 세계적인 수준이지만, LIB 열폭주로 인한 사고의 심각성을 고려할 때, 지속적인 연구개발, 엄격한 안전관리, 승조원 교육이 필요하다. 이를 통해 LIB의 안전성을 확보하고, 잠수함 운용의 신뢰성을 높여야 한다.

Abstract

This study analyzes the fundamental concepts, thermal runaway mechanisms, and maritime incident cases of lithium-ion batteries (LIBs) used in submarines. Additionally, it examines the current research on improving thermal runaway and the state of safety design for submarine LIB systems. Submarine LIBs are designed with multi-layered safety mechanisms and have passed rigorous validation tests, meeting all safety standards. Despite the world-class level of LIB and ESS technology in South Korea, the severity of incidents caused by LIB thermal runaway underscores the need for continuous research and development, stringent safety management, and crew education. These measures are essential to ensure the safety of LIBs and enhance the reliability of submarine operations.
