Abstract

A method for manufacturing a current collector layer is provided. The method comprises: forking a release layer on a surface of a film; forming an adhesive layer on the release layer; forming a metal layer on the adhesive layer; and removing the film and the release layer.

First claim

What is claimed is:

1 . A method for manufacturing a current collector layer, comprising:
forming a release layer on a surface of a film; forming an adhesive layer on the release layer; forming a metal layer on the adhesive layer; and removing the film and the release layer.

2 . The method for manufacturing the current collector layer according to claim 1 , wherein the step of forming the release layer on the surface of the film includes:
coating a release agent on the surface of the film; and performing a drying treatment to the release agent.

3 . The method for manufacturing the current collector layer according to claim 2 , wherein the release agent includes one or a combination selected from the group consisting a fluorine-containing organic compound, a chlorine-containing polymer and a silicon-containing organic compound.

4 . The method for manufacturing the current collector layer according to claim 3 , wherein the fluorine-containing organic compound include one or a combination selected from the group consisting polytetrafluoroethene (PTEF), polyvinylidene difluoride (PVDF) and fluorinated ethylene propylene copolymer (FEP).

5 . The method for manufacturing the current collector layer according to claim 3 , wherein the chlorine-containing polymer includes polyvinyl chloride (PVC), and the silicon-containing organic compound includes polyester and/or silicone resin.

6 . The method for manufacturing the current collector layer according to claim 1 , wherein a surface treatment is performed onto the release layer before the adhesive layer is formed on the release layer.

7 . The method for manufacturing the current collector layer according to claim 6 , wherein the surface treatment includes one or a combination selected from the group consisting a plasma treatment, an ion source treatment and a spark treatment.

8 . The method for manufacturing the current collector layer according to claim 1 , wherein the material of the adhesive layer includes silicon oxide and/or titanium oxide.

9 . The method for manufacturing the current collector layer according to claim 1 , wherein a method for forming the metal layer includes a wet deposition method, and the wet deposition method includes electroplating and/or chemical plating.

10 . The method for manufacturing the current collector layer according to claim 1 , wherein the material of the film includes one or a combination selected from the group consisting polyethylene terephthalate (PET), polycarbonate (PC) and polymethyl methacrylate (PMMA).
