Abstract: 본 발명은 인산리튬 수용액을 전기분해하여 리튬을 제조하는 방법에 관한 것으로, 양극이 포함된 양극셀과 음극이 포함된 음극셀이 양이온 교환막에 의해 구획된 전해장치를 준비하고, 상기 양극셀에 인산리튬 수용액을 투입하고, 상기 음극셀에 수용액을 투입한 후, 전류를 인가하여 양극셀에서 분리된 리튬 이온을 상기 음극셀로 이동시켜 전기분해 환원하는 것을 특징으로 하는 인산리튬 수용액의 전기분해에 의한 리튬 제조 방법을 제공한다.
본 발명에 의하면, 종래의 복잡한 전해장치의 구조를 단순화시켜 전해 전압의 저하를 기대할 수 있고 전해에 필요한 전력의 소모가 낮으며, 조해성을 갖는 염화리튬을 사용하지 않음으로써 취급이 용이하고 염소가스의 미발생으로 전해장치에 부식이 방지되는 동시에 무해화 처리를 위한 설비의 도입이 불필요하기 때문에 친환경적이면서도 저비용으로 금속 리튬을 고순도로 제조할 수 있다.-
