PURPOSE: An Sn or Ce ion-added electrolytes for soluble lead redox flow battery and batteries comprising the same are provided to control the discharge time by controlling the crystallinity and the micro structure of a Pb layer or PbO2 layer formed on an electrode in the charge of a soluble lead redox flow battery. CONSTITUTION: Sn or Ce ions are added to electrolytes for soluble lead redox flow battery, wherein the supply source of Sn ions is sulfonic acid tin and the supply source of Ce ions is carium carbonate. The concentration of Sn or Ce ions is 0.005~0.02M. A soluble lead redox flow battery comprises a cell including a positive electrode and a negative electrode, a tank storing the electrolyte for a soluble lead redox flow battery, and a pump circulating the electrolyte into the cell.
