Abstract

The invention relates to the field of lithium batteries, in particular to a lithium battery copper foil surface pretreatment device capable of improving material performance. The technical problem to be solved is: when the crystallization of the copper foil roughening layer is on the second electroplating protection layer, it is easily caused to fall off by the impact of the solution. The technical embodiment of the present invention is: a lithium battery copper foil surface pretreatment device that can improve material performance, including a first mounting frame, a secondary deposition unit and a protection unit; the upper surface of the first mounting frame is connected with a A secondary deposition unit for plating a protective layer on the lower surface of the copper foil; the secondary deposition unit is connected with a protection unit for protecting dendrites on the surface of the deposited copper foil. The present invention protects the dendrites on the copper foil when the protective layer is plated on the copper foil, so as to prevent the loose dendrites on the copper foil from falling off due to the impact of the solution when they enter the plating solution. If the situation occurs, preventing dendrites from falling off leads to a decrease in the bond between the roughened layer and the resin.

Description

Technical field [0001] The present invention relates to a lithium battery, and more particularly relates to an improved material properties lithium foil surface pretreatment device. Background technique [0002] With the rapid development of new energy industries, also increased demand for lithium batteries; [0003] Currently lithium ion battery harsh operating environment and performance requirements, thickness, oxidation resistance and adhesion properties of the copper foil made various requirements; [0004] Wherein, due to the smooth surface of the copper foil, the binder resin is weak, the weak adhesive property of the copper foil, severely limits the development of a lithium battery, it is necessary and dendritic layer of copper plated copper oxide crystals on the surface of the copper foil roughened layer, for increasing the roughness of the copper foil surface to increase the adhesion of the copper foil and the resin; [0005] A copper foil layer adhered to the roughened...
