るという効果がある。H. Effects of the invention As detailed above, according to the current collecting electrode for a zinc-bromine battery of the present invention, a busbar is arranged on the top surface of the current collecting mesh, and terminals are electrically connected on the plane of this busbar. The two flat parts of the current collecting mesh were sandwiched between carbon plastic plates and heat pressed to integrate them, and then a frame plate was integrally installed around the mesh to form a current collecting electrode. The busbars arranged to cross the plane of the mesh can collect current evenly without concentrating the current in one place, and the current can be taken out directly from the terminals attached to this busbar, so it is possible to collect current evenly without concentrating the current in one place. This has the effect that the structure can be simplified compared to a configuration in which bus bars are attached to each part of the current collecting mesh extending on both sides of the electrode, and terminals are pulled out from these two locations.

ン成形が容易かつ確実になり、製品の歩留まりを
向上できるという効果がある。 In addition, since the current collector mesh and carbon plastic plate are heat pressed and then molded in two steps, the molding conditions are stabilized, and the injection molding is easy and reliable, making it possible to improve the quality of the product. This has the effect of improving yield.

とができるとう効果がある。 Furthermore, the current collector mesh is wrapped inside the carbon plastic plate and the frame plate,
Since this external electrolytic solution etc. does not come into contact with the current collecting mesh, there is an effect that corrosion of the current collecting mesh can be prevented.
