Abstract

Structural battery has been researched extensively to combine the functions of the battery and structure without gravimetric or volumetric increments compared to their individual components. The main idea is to employ carbon fabric as the reinforcement and electrode, glass fabric as the separator, and solid-state electrolyte which can transfer load. However, state-of-the-art solid-state electrolytes do not have sufficient load carrying functionality and exhibiting appropriate ion conductivity simultaneously. Therefore, in this research, a system which has both battery and load carrying capabilities using glass fabric separator and liquid electrolyte was devised and tested to investigate the potential and feasibility of this structural battery system and observe electric properties. It was observed that elongating separator decreased electrical behavior stability. A possible cause of this phenomenon was the elongated glass fabric separator inadequately preventing the penetration of small particles of the cathode material into the anode. This problem was verified additionally by using a commercial separator. The characteristic of the glass fabric and the interface between the electrode and glass fabric needed to be further studied for the realization of such a load carrying structural battery system.

질량 및 부피 증가없이 전지와 구조물기능을 복합재에 결합시키는 구조전지 연구가 광범위하게 진행되고 있다. 탄소섬유 및 유리섬유를 하중지지 및 음극, 분리막 용도로 사용하고, 하중전달이 가능한 고체전해질을 모재로 쓰는 것이 현재 아이디어 이지만, 고체전해질이 두 성능을 충분히 만족시키지 못하는 수준이라 구조전지를 구현하지 못하고 있는 실정이다. 그래서, 본 연구는 유리섬유 분리막 및 액체전해질을 사용하여 하중지지 및 전지의 기능을 동시에 수행하는 실험을 구성하여 액체전해액을 사용한 구조전지의 가능성 및 전기적 물성 변화를 관찰하였다. 인장된 분리막은 안정성을 떨어트리는 영향을 미치는데, 이는 양극의 미세입자들이 늘어난 유리섬유의 틈새로 침투하는 것을 분리막이 막지 못하기 때문이라 예상하였고, 상용 분리막을 추가로 사용 하여 그 예상되는 원인을 확인해 보았다. 그리고, 이러한 구조전지 시스템을 구현하기 위해서는 유리섬유 특성의 연구와 전극과 분리막의 계면에 대한 연구가 필요하다.
