Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but it does not constitute any limitation to the present invention.

[0020] refer to image 3 , Figure 4 As shown in FIG. 1 , a device for double-sided synchronous roughening of electrolytic copper foil includes pickling tank 2, roughening tank 3, curing tank 4, water washing tank 5 and oxidation prevention tank 6. Among them, the bottoms of the roughening tank 3 and the curing tank 4 are respectively provided with a first electrolyte PVC inlet pipe 9 and a second electrolyte PVC inlet pipe 10, and a third electrolytic solution is provided at a position 10 cm away from the upper end of the roller in the liquid. The liquid PVC inlet pipe 11 is used to change the flow structure of the solution in the roughening tank and the solidification tank, to ensure the flow process requirements of the roughening solution and the solidification solution, and to make the surface of ...

Abstract

The invention relates to a method for synchronously roughening both surfaces of an electrolytic copper foil and equipment thereof, which belong to the technical field of electrolytic copper foils. The technical key point is that: corresponding anode plates are arranged on a smooth surface and a rough surface and electrolyte flows through the space between the electrolytic copper foil and the anode plates when the electrolytic copper foil passes through a roughening groove and a solidifying groove so as to perform electroplating copper precipitation treatment on the smooth surface and the rough surface of the electrolytic copper foil synchronously at a time, wherein the electroplating anode plates in the roughening groove and the solidifying groove of the used equipment are distributed in the middle and on the front side of a groove body. Compared with the prior art, the method for synchronously roughening both surfaces of the electrolytic copper foil and the used equipment thereof have the advantages that: the smooth surface and the rough surface of the copper foil can be synchronously electroplated at a time, so that production efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a method for roughening electrolytic copper foil, in particular to a method for synchronous roughening of both sides of electrolytic copper foil. The invention also relates to equipment for synchronous roughening of both sides of electrolytic copper foil, which belongs to the technical field of electrolytic copper foil. Background technique [0002] Compared with the electrolytic copper foil for copper-clad laminates, the double-sided roughened electrolytic copper foil for lithium-ion power batteries has a large difference in performance indicators. The mechanical measurement thickness of double-sided roughened electrolytic copper foil for lithium-ion power batteries is ≤12 microns, The crystal structure of the smooth surface and the rough surface is dense and uniform, the roughness of the smooth surface is ≤2.5 microns, the metal density is close to the theoretical density of copper, the elongation is ≥5%, and the tensile stren...
