Abstract:
본 발명은 아연 공기 이차 전지용 양극에 관한 것으로서, A 1-x A' x B 1-y B' y O 3 의 페로브스카이트(Perovskite) 구조를 갖는 물질을 양극 촉매로 사용하는 아연 공기 이차 전지용 양극 촉매에 있어서, A 자리의 양이온은 Pr 3+ , A' 자리의 양이온은 Sr 2+ 또는 Ca 2+ 로 치환할 수 있으며, 이 때 x=0~0.5의 범위를 갖고, B 자리의 양이온은 Mn 3+ , Co 3+ 또는 Ni 3+ , B' 자리의 양이온은 Fe 3+ 로 치환할 수 있으며, 이 때 y=0~0.5의 범위를 갖는 것을 특징으로 하는 아연 공기 이차 전지용 양극 촉매 그리고 이러한 양극 촉매 물질의 합성방법 및 이를 이용한 양극의 제조방법을 기술적 요지로 한다. 이에 따라, ABO 3 구조를 갖는 페로브스카이트 구조의 양극 촉매 물질을 합성하고, 이를 양극으로 사용함으로써 촉매의 활성을 강화할 수 있고, A 또는 B 양이온을 원자가가 다른 A' 또는 B' 양이온으로 치환하면 산소결핍농도가 증가하고 산소 이온의 전도성을 증가시켜 결과적으로 촉매의 반응성이 증가하게 되므로, 충방전 특성이 우수하고 부식 반응이 없어 안정적인 아연 공기 이차 전지용 양극을 제공할 뿐만 아니라, 비교적 저가의 물질로 양극을 제조할 수가 있어 경제적인 이점이 있다. 아연 공기 이차 전지 페로브스카이트 양극 촉매
