Disclosed is a solution circulation type metal-halogen battery in which an electrolyte is circulated between a reaction tank and an electrolyte storage tank. This battery has a first group of rectifying plates and a second group of rectifying plates aligned in a row, respectively, so as to partition between the inlet of the electrolyte and the reaction tank and between the outlet thereof and the reaction tank, respectively. These first and second groups of rectifying plates are formed in such a manner that the interval between the respective rectifying plates increases in accordance with a predetermined functional equation in the direction of moving away from the inlet or outlet side of the electrolyte. This apparatus equalizes the flow rate and velocity of the electrolyte flowing through the reaction tank, thereby preventing the occurrence of an overvoltage or a faulty deposition of metal resulting from the non-uniform flow of the electrolyte.
