초록

알루미늄-공기 전지의 성능을 향상시키기 위해서는 전극의 전기화학적 특성에 미치는 전해질의 영향을 이해하는 것이 매우 중요하다. 본 연구에서는 NaCl, LiCl, CaCl2, ZnCl2와 같이 동일한 음이온을 가지나 양이온이 다른 전해질을 사용하여 음극과 양극에서 진행되는 전기화학적 산화·환원 반응에 미치는 전해질 양이온의 영향에 관하여 조사하였다. 전극의 방전 전위 및 비용량에 전해질 양이온이 영향을 준다는 것이 방전 시험, 주사전자현미경과 X-선 회절 분석에 의해 확인되었다. NaCl과 LiCl 전해질 용액 중에서 상대적으로 높은 셀 전압과 비용량이 얻어졌다. 양극 표면에는 Ca2+와 Zn2+ 이온에 의해 전극 반응을 방해하는 침전물이 생성되었으며, 이로 인해 양극 성능이 저하되었다. 게다가 Ca2+ 이온은 음극의 부동태화를 유발하면서 음극의 성능 저하를 촉진시켰다. 이것은 전해질의 양이온이 양극과 음극의 전기화학적 성능에 각각 다른 영향을 주고 있음을 시사하는 것이다.

To improve the performance of aluminum-air batteries, it is very important to understand the effect of electrolytes on the electrochemical properties of electrodes. In this study, the effects of electrolyte cations on the electrochemical redox reactions proceeding at the negative and positive electrodes were investigated using electrolytes having the same anion but different cations such as NaCl, LiCl, CaCl2, and ZnCl2. It was confirmed by discharge test, scanning electron microscopy and X-ray diffraction analysis that electrolyte cations affect the discharge potential and specific capacity of the electrode. Precipitates were formed on the surface of the positive electrode by Ca2+ and Zn2+ ions, resulting in degradation of the performance of the positive electrode. In addition, Ca2+ ions passivated the negative electrode and accelerated the performance degradation. This suggests that the positive ions of the electrolyte have different effects on the electrochemical performance of the positive and negative electrodes.
