Claim:
1. A method, comprising: providing a first carrier substrate; depositing a first release layer on the first carrier substrate, wherein a mean peak to valley roughness of a surface of the first release layer opposite the first carrier substrate is between about 0.1 μm and about 1 μm, and wherein the first release layer has a thickness of greater than or equal to about 2 μm; depositing a first protective layer on the surface of the first release layer; depositing a first electroactive material layer on the first protective layer, wherein an adhesive strength between the first release layer and the first protective layer is greater than an adhesive strength between the first release layer and the first carrier substrate; delaminating the first carrier substrate from the first release layer; and removing the first release layer from the first protective layer by dissolving the first release layer in an electrolyte.
