As shown in the figure, each electrode 50 and separator 3 are stacked, sandwiched from both sides by end plates 12 and 13, and are integrally connected as a whole with a tightening bolt and a tightening nut. The positive electrode side electrolyte 9 is supplied to the surface of the electrode plate 17 of the positive electrode chamber 7 from the inlet 18a through the manifold 14, channel 15 and microchannel 16 of each electrode 50, and is supplied again through the positive electrode storage tank 8 from the outlet 19a.

の工夫が必要となる。D Problems to be Solved by the Invention Incidentally, in the negative electrode chamber 4 and the positive electrode chamber 7, microchannels 16 are provided in the upper and lower portions of the electrodes 50 in order to obtain a uniform electrode reaction. However, although the microchannel 16 makes the flow distribution of the electrolytic solution uniform, the pressure loss against the flow is large and reduces the flow rate. Particularly on the positive electrode chamber 7 side, as charging progresses, the bromine complexing agent and bromine added to the electrolyte generate a bromine complex, and the viscosity of the positive electrode side electrolyte 9 increases.
The flow rate will further decrease. If the flow rate of the positive electrode electrolyte 9 decreases, sufficient bromine necessary for the reaction during charging will not be supplied to the positive electrode 1, resulting in a decrease in Coulombic efficiency. Therefore, in order to increase the Coulombic efficiency, it is necessary to devise an electrode that can obtain a uniform flow velocity distribution and a large flow rate on the positive electrode 1 side.

Since the distance is greater than the distance to the separator, the cross section through which the electrolyte flows in the positive electrode chamber is larger than the cross section through which the electrolyte flows in the negative electrode chamber. For this reason, sufficient bromine can be used to counter the increase in the viscosity of the positive electrode electrolyte due to the formation of bromine complexes during the latter half of charging and the first half of discharging, and the accompanying decrease in the amount of positive electrode electrolyte relative to the amount of negative electrode electrolyte. can be supplied to the positive electrode.

An insulating frame made of polyolefin resin is formed around the entire circumference on each side of the negative electrode chamber 4, and the insulating frame 51 on the side of the positive electrode chamber 7 is formed higher than the insulating frame 52 on the side of the negative electrode chamber 4 (for example, the insulating frame 51 height 1.8mm,
Height of insulation frame 52: 0.8 mm). Furthermore, microchannels 16a and 16b are formed on both sides of the electrolyte inflow and outflow portions of the electrode 50, and are made of the same material as the insulating frames 51 and 52 and are integrally formed with the insulating frames 51 and 52. It coincides with the surfaces of frames 51 and 52. Electrode plate 1 made of carbon plastic and integrally molded with insulating frames 51 and 52 on the positive electrode chamber 7 side and the negative electrode chamber 4 side
7 is provided with grid-shaped polyolefin resin supporters 20a and 20b extending over the height of the insulating frames 51 and 52.

等実用的効果を奏するものである。 As described above, in the present invention, the height of the insulating frame 51 and the microchannel 16a on the positive electrode chamber 7 side is formed higher than those on the negative electrode chamber 4 side, so that the electrolytic solution flows between the positive electrode chamber 7 and the microchannel 16a. As the cross section increases, the flow resistance of the electrolytic solution decreases and the flow rate increases, making it possible to supply sufficient bromine to the positive electrode chamber 7. Therefore, the movement of the bromine complex in the positive electrode chamber 7 is further improved, and practical effects such as the ability to increase the Coulombic efficiency are achieved.

A grid-like supporter was placed on the electrode surface. When the positive electrode area is 750cm2 ,
Positive electrode side electrolyte flow rate from 200ml/min to 450~500mm/
Therefore, the Coulombic efficiency showed an increase of more than 10%.

Effects of the invention As explained above, the present invention is designed to reduce the distance from the electrode surface of the positive electrode chamber surrounded by the positive electrode, the insulating frame, and the separator to the negative electrode chamber surrounded by the negative electrode, the insulating frame, and the separator. Since the distance is larger than the distance from the electrode surface to the separator, the cross section through which the electrolyte flows in the positive electrode chamber is larger than the cross section through which the electrolyte flows in the negative electrode chamber. For this reason, sufficient bromine can be used to counter the increase in the viscosity of the positive electrode electrolyte due to the formation of bromine complexes during the latter half of charging and the first half of discharging, and the accompanying decrease in the amount of positive electrode electrolyte relative to the amount of negative electrode electrolyte. can be supplied to the positive electrode, which has the effect of increasing the Coulombic efficiency of the battery.
