The present invention relates to an electrolyte containing vanadium ions, and a secondary battery comprising same, and, more specifically, to an electrolyte containing vanadium ions, the electrolyte having concentrations of vanadium ions and an acidic solution that are adjusted to be different in a cathode electrolyte and an anode electrolyte, which are used in a secondary battery using an electrolyte containing vanadium ions, so as to lower the self-discharge rate of a secondary battery, thereby enabling performance to be enhanced. La présente invention concerne un électrolyte contenant des ions vanadium, et une batterie secondaire le comprenant, et, plus spécifiquement, un électrolyte contenant des ions vanadium, l'électrolyte ayant des concentrations en ions vanadium et une solution acide qui sont ajustées pour être différentes dans un électrolyte de cathode et un électrolyte d'anode, qui sont utilisés dans une batterie secondaire faisant appel à un électrolyte contenant des ions vanadium, de manière à abaisser le taux d'auto-décharge d'une batterie secondaire, ce qui permet d'améliorer les performances. 본 발명은 바나듐 이온을 포함하는 전해액 및 이를 포함하는 이차전지에 관한 것으로, 보다 상세하게는 바나듐 이온을 포함하는 전해액을 사용하는 이차전지에 사용되는 양극 전해액 및 음극 전해액의 바나듐 이온 및 산성 용액의 농도를 다르게 조절함으로써, 이차전지의 자가 방전율을 낮추어 성능을 향상시킬 수 있는 바나듐 이온을 포함하는 전해액에 관한 것이다.
