The existing copper foil production method mainly has two kinds, one is calendered copper foil, which is formed by repeatedly rolling-copper band-annealing, and the thickness reaches micron level, and the ductility, bending resistance and conductivity are good. The other is electrolytic copper foil, which is formed by electrolytic deposition of ionized copper ion solution, usually copper sulfate solution, such as the content shown in the patents with application publication numbers CN109735879A and CN117684220A. However, in the existing electrolytic copper foil structure, the anode needs to be directly contacted with the plating solution, and the plating solution itself has strong corrosive property, and the electrolysis process also affects the electrode, so a relatively stable titanium metal material is usually used as the electrolysis electrode, or titanium is fully wrapped with copper to prolong the service life of the electrode. However, the conductive performance of titanium material itself is poor, which increases power consumption on the one hand, and leads to serious heating of the electrode during electrolysis on the other hand, which also affects the service life of the electrode, and the value of titanium material itself is high, which increases the production cost. Therefore, a low-cost, corrosion-resistant and conductive anode copper bar is needed. SUMMARY

[0023] Example 1:

[0024] like Figures 1-3 As shown, an anode conductive copper busbar with surface treatment of electrolytic copper foil includes a copper plate 1 and a titanium-coated layer 2, which is formed by electroplating. The thickness of the titanium-coated layer 2 should not be too thick, as this would reduce conductivity, nor should it be too thin, as this would result in poor protection of the internal copper plate 1. The optimal thickness range of the titanium-coated layer 2 is 0.01 mm to 1 mm, and in this example, a 0.1 mm titanium-coated layer 2 is used. The copper plate 1 includes an upper plate 11, a lower plate 12, and a connecting plate 13. The connecting plate 13 is located between the upper plate 11 and the lower plate 12, and the connecting plate 13, the upper plate 11, and the lower plate 12 form a Z-shaped structure, so that the upper plate 11 and the lower plate 12 are in different planes, forming a layer in height between them. The connecting plate 13, the upper plate 11, and the lower plate 12 are integrally formed, which improves the overall conductivity. The titanium-coated layer 2 is located on the lower plate 12 and at one end of the connecting plate 13 near the lower plate 12.

[0025] The connecting plate 13 is perpendicular to the upper plate 11 and the lower plate 12, respectively. The titanium-coated layer 2 on the connecting plate 13 extends at least half the length of the connecting plate 13, ensuring that the lower plate 12 can be fully immersed in the electrolyte, and that the electrolyte does not exceed the height of the titanium-coated layer 2 on the connecting plate 13. In use, the lower plate 12 covered with the titanium-coated layer 2 and part of the connecting plate 13 are immersed in the electroplating solution, while the upper plate 11 and the other part of the connecting plate 13 are exposed to the air and connected to the external anode 3 to achieve energization.

[0026] The upper plate 11 is provided with a first connecting hole 14 for connecting with the external anode 3; the upper surface of the upper plate 11 is attached to the external anode 3. The upper surface of the upper plate 11 is also provided with a clamping groove 16 for quick disassembly; one end of the clamping groove 16 penetrates the upper plate 11 away from the end of the connecting plate 13; the clamping groove 16 is used for cooperating with the clamping block 31 on the anode 3; the cross section of the clamping groove 16 is a trapezoid with a narrow upper surface and a wide lower surface; inserting the clamping block 31 on the anode 3 into the clamping groove 16 can realize quick butt joint of the anode 3 and the copper plate 1, and then tightening the screw nut realizes fastening, compared with the traditional plane attachment butt joint, which is convenient for disassembly, and increases the contact area between the two and enhances the conductive effect and reduces the conductive loss.

[0027] The clamping groove 16 is provided with a baffle 17 at the end of the upper plate 11 close to the connecting plate 13, and the baffle 17 is integrally made with the connecting plate 13; the baffle 17 can block the anode 3 inserted into the clamping groove 16, and the screw mounting hole on the anode 3 is aligned with the first connecting hole 14 on the upper plate 11, which is convenient for connection.

[0028] The lower plate 12 is provided with a second connecting hole 15 for fixing with the internal structure of the external electrolytic cell.

[0029] In the implementation process, the partially covered titanium coating layer 2 protects the part of the copper plate 1 immersed in the electrolyte, prevents the copper plate 1 from being corroded by the electrolyte, prolongs the service life of the copper plate 1, and ensures that the overall conductive performance of the copper plate 1 and the titanium coating layer 2 is good, reduces the heat loss of titanium material, and reduces the cost of using titanium material; the clamping groove 16 cooperates with the baffle 17 to facilitate quick butt joint and disassembly with the anode 3.

[0030] The above description is only one specific example of the present application and does not constitute any limitation on the present application. Obviously, for those skilled in the art, after understanding the content and principle of the present application, various modifications and changes in form and details can be made without departing from the principle and structure of the present application, but these modifications and changes based on the idea of the present application are still within the protection scope of the claims of the present application.
