The battery case (1) and the current collector (6C), the i-cell (1) and the zinc electrode plate (2'), and the zinc electrode plate (2') and the collector Because fluid is likely to leak in the direction of the arrow shown in Figure 1 through the gap between the magnetic body (6), this part (2) is strictly masked to prevent fluid leakage. However, due to the structure of the battery, sufficient masking is required. In addition, there is no suitable material with high corrosion resistance due to the use of liquid fluorogen, and the present invention aims to avoid the decrease in energy efficiency caused by the liquid junction 62. As a result of the study, 13t' of zinc-halogen heavy oil with a bipolar structure that can effectively prevent liquid leakage from unit cells in the series direction was used.
In one shot, an aqueous solution containing zinc halide as the main component is used as the electrolyte, a zinc electrode plate is placed oppositely as a negative electrode, and a halogen electrode plate is used as a positive electrode, and the mini-electrolyte is passed through the halogen electrode plate to form a mini-electrolyte between the two electrodes. In heavy oil, a large number of bipolar unit cells to be supplied are connected in parallel and in series (C). It is characterized by this.
