Summary:The present invention relates to a method for preparing a high concentration vanadium electrolyte for a vanadium redox flow battery and, more specifically, to a method for preparing a high concentration vanadium electrolyte of 1.8 M or more by using ammonium metavanadate (AMV). By performing phase transition of AMV and forming ammonium polyvanadate (APV), impurities can be minimized. 본 발명은 바나듐 레독스 흐름전지용 고농도 바나듐 전해액 제조방법에 관한 것으로서, 좀 더 자세하게는 암모늄 메타바나데이트를 이용하여 1.8M 이상의 고농도 바나듐 전해액을 제조하는 방법에 관한 것이다. 본 발명은 암모늄 메타바나데이트(AMV)를 상전이 시켜 암모늄 폴리바나데이트(APV)를 형성하고 이를 포함함으로써 불순물을 최소화할 수 있는 고농도 바나듐 전해액 제조방법을 제공한다.
