신재생에너지의 문제점은 무엇인가? | 심각한 환경 오염과 화석 에너지의 고갈 문제로 인해 신재생에너지 사용이 강조되고 있다. 태양광, 태양열 에너지, 풍력 에너지의 발전은 매우 급격하게 이루어지고 있지만 이러한 에너지의 공급 자체가날씨에영향을많이받기때문에지속적인에너지공급에문제가있다. 이러한문제를해결하기위해에너지저장시스템(Energy Storage System, ESS)은 신재생에너지 발전에 필수적인 요소가 되었다. | |
유기 물질의 특징은 무엇인가? | 이에 따라 활물질을 유기 물질로 대체하고자 하는 연구가 많이 진행되고 있다[17-25]. 유기 물질은 금속 활물질보다 풍부하고, 가격이 저렴하기 때문이다. 먼저 비수계 전해질을 기반으로 한 레독스 플로우 배터리는 물 분해의 전압(약 1. | |
비수계 전해질을 기반으로 레독스 플로우 배터리의 단점은 무엇인가? | 유기 물질은 금속 활물질보다 풍부하고, 가격이 저렴하기 때문이다. 먼저 비수계 전해질을 기반으로 한 레독스 플로우 배터리는 물 분해의 전압(약 1.23 V) 보다 높은 전압을 낼 수 있다는 것이 장점이다. 하지만, 낮은 용해도와 활물질의 불안정성 때문에 에너지 밀도가 낮고 사고의 위험이 크다[26]. |
