Abstract

Demand and interest in electric vehicles are increasing rapidly due to environmental issues. Improving the performance of electric vehicles requires the development of automotive batteries and battery joining technologies. Aluminum alloys are the most widely used metals in the electric vehicle industry, and aluminum bonding is used in all processes comprising automotive batteries. Therefore, in this paper, based on the characteristics of aluminum and aluminum alloys and knowledge of various aluminum joining technologies, the main and the next generation bonding technologies used in automotive battery are reviewed. It also explains the structure of automotive secondary battery cells and the integration order of 'cell-module-pack' where joining is used in the process, also various environmental conditions that must be considered when joining.

환경이슈로 인해 전기자동차에 대한 수요 및 관심이 급증하고 있다. 전기자동차의 성능 향상에는 핵심 부품인 자동차 배터리의 성능향상, 그리고 배터리 접합기술의 발전이 수반되어야 한다. 알루미늄 합금은 전기자동차 산업에서 가장 폭넓게 사용되는 금속이며, 알루미늄 접합은 전기자동차 이차전지를 구성하는 모든 공정에서 이용된다. 따라서 본 논문에서는 알루미늄, 알루미늄 합금의 특성과 다양한 알루미늄 접합 기술에 대한 지식을 기반으로, 차량용 이차전지에서 이용되는 주요한 접합기술과 차세대 접합기술을 검토한다. 또한 그 과정에서 접합이 이용되는 자동차 이차전지 셀의 구조, '셀-모듈-팩'의 집적 순서와, 접합 기술이 요구하는 다양한 환경적 조건들을 설명한다.
