Mixing device for electrolyte

The present invention relates to an electrolyte mixing device for mixing an electrolyte received in a case which can stably mix with the minimum amount of movements while having a small installation space as a structure is simple. The electrolyte mixing device comprises: a separation wall formed in the case to divide the inside of the case into a plurality of space units, and forming a pair of mixing holes vertically separated from each other; a lower opening and closing means for opening and closing a lower mixing hole from the pair of mixing holes; and an upper opening and closing means for opening and closing an upper mixing hole from the pair of mixing holes. 본 발명은, 케이스 내에 수용되는 전해액을 혼합시키는 전해액 혼합장치에 있어서, 케이스 내부를 복수개의 공간부로 구획되도록 케이스 내측에 형성되며, 상하로 서로 이격되는 한 쌍의 혼합공이 형성된 분리벽, 한 쌍의 혼합공 중 하측의 혼합공을 개폐하는 하부개폐수단, 한 쌍의 혼합공 중 상측의 혼합공을 개폐하는 상부개폐수단을 포함하는 전해액 혼합장치를 제공한다.
