Abstract

A method of manufacturing a battery is provided. The steps are as follows: forming an anode material and a cathode material on a first side and a second side of an isolation film, respectively, wherein the first side is opposite to the second side; forming a first protection layer on the first side of the isolation film; forming a first metal layer on the second side of the isolation film; forming a second protection layer on the first metal layer; removing the first protection layer; forming a second metal layer on the first side of the isolation film; and removing the second protection layer.

First claim

What is claimed is:

1. A method of manufacturing a battery, comprising:
forming an anode material and a cathode material on a first side and a second side of an isolation film, respectively, wherein the first side is opposite to the second side;
forming a first protection layer on the anode material;
forming a first metal layer on the cathode material, wherein the cathode material is located between the isolation film and the first metal layer;
forming a second protection layer on the first metal layer;
removing the first protection layer;
forming a second metal layer on the anode material, wherein the anode material is located between the isolation film and the second metal layer; and
removing the second protection layer.

2. The method of manufacturing a battery according to claim 1 , wherein after forming the anode material and the cathode material, the method further comprises:
drying the isolation film; and
bonding the anode material and the cathode material.

3. The method of manufacturing a battery according to claim 1 , wherein the anode material and the cathode material are formed by a wet deposition method.

4. The method of manufacturing a battery according to claim 1 , wherein the anode material and the cathode material are formed via continuous steps or non-continuous steps.

5. The method of manufacturing a battery according to claim 1 , wherein the first metal layer and the second metal layer are formed via a dry deposition method or a wet deposition method.

6. The method of manufacturing a battery according to claim 1 , wherein the material of the first protection layer and the second protection layer are strippable materials, respectively.

7. The method of manufacturing a battery according to claim 6 , wherein the strippable material includes a resin material.

8. The method of manufacturing a battery according to claim 1 , wherein the first protection layer and the second protection layer are formed by a wet deposition method.

9. The method of manufacturing a battery according to claim 1 , before forming the cathode material and the anode material, further comprising:
forming a sealing material on the surface of the isolation film.

10. The method of manufacturing a battery according to claim 9 , wherein the sealing material includes a ceramic material.
