Traditional collector electrode for zinc bromine flow battery adopts copper material to make, and adopts punching copper coin, welding copper mesh, braiding copper mesh more, and stretching copper mesh etc., at corresponding site welding leading-out terminal, are made collector electrode.Because the coefficient of expansion of copper product and conductive plastics has a long way to go, the termination electrode of making easily produces buckling deformation, affects pile assembly quality, and easily causes sealing-off.
Utility model content
The purpose of this utility model is, a kind of new zinc bromine flow battery collector electrode is provided, and it can effectively solve collector electrode, in when assembling, the problem of buckling deformation occur, and effectively ensures assembly quality, prevents sealing-off.
The technical solution of the utility model: a kind of new zinc bromine flow battery collector electrode, comprise collector plate and leading-out terminal, collector plate and leading-out terminal are integral type structure, collector plate is formed by connecting by several sub-electrode plates.Adopt integral structure to replace traditional Welding Structure, efficiently solve the problem of sealing-off.
In aforesaid new zinc bromine flow battery collector electrode, the quantity of described sub-electrode plate is 30～80.
In aforesaid new zinc bromine flow battery collector electrode, the quantity of described sub-electrode plate is 54.
In aforesaid new zinc bromine flow battery collector electrode, described sub-electrode plate is arranged according to the mode of 6*9.
In aforesaid new zinc bromine flow battery collector electrode, the thickness of described collector plate and leading-out terminal is 0.5mm～1.5mm.
In preferred new zinc bromine flow battery collector electrode, the thickness of described collector plate and leading-out terminal is 1.0mm.
In aforesaid new zinc bromine flow battery collector electrode, described collector plate and leading-out terminal all adopt copper coin to make.
In aforesaid new zinc bromine flow battery collector electrode, sub-electrode plate is formed by connecting by 4 U-shaped electrode slices, wherein upper left U-shaped electrode slice opening is towards opening down, the bottom-right U-shaped electrode slice opening of the U-shaped electrode slice of a left side, lower left towards the right side, and top-right U-shaped electrode slice is opening up.The center of sub-electrode plate is the junction of 4 U-shaped electrode slices.Adopt no matter this structure is in the process using or while assembling, can both effectively prevent buckling deformation.
In aforesaid new zinc bromine flow battery collector electrode, between described any 2 sub-battery lead plates are equal, connect by 2 copper sheets.
Compared with prior art, the utility model is by collector plate and leading-out terminal being designed to integral type design, without independent welding, and accident that can generating material sealing-off when ensureing in processing and using.In addition, adopt unique collector plate structural design, make collector plate behind termination electrode inside, can follow conductive plastics in die casting and stretch to any direction, in termination electrode processing and use procedure, avoided the buckling deformation problem causing due to bi-material expansion coefficient difference.
Brief description of the drawings
