METHOD FOR MANUFACTURING ELECTRODE FOR POWER STORAGE DEVICE AND METHOD FOR MANUFACTURING POWER STORAGE DEVICE
First Claim
1. A method for manufacturing an electrode for a power storage device, the method comprising the steps of:
- forming a conductive body functioning as a current collector;
forming a mixed layer including an amorphous region and a microcrystalline region over one of surfaces of the conductive body; and
etching the mixed layer selectively, so that a part of or a whole of the amorphous region is removed and the microcrystalline region is exposed, thereby, forming an active material of the electrode for the power storage device.

Abstract
One of objects is to reduce the effect caused by the volume expansion of an active material. An embodiment is a method for manufacturing an electrode for a power storage device which includes an active material over one of surfaces of a current collector. The active material is formed by forming a conductive body functioning as the current collector; forming a mixed layer including an amorphous region and a microcrystalline region over one of surfaces of the conductive body; and etching the mixed layer selectively, so that a part of or the whole of the amorphous region is removed and the microcrystalline region is exposed. Thus, the effect caused by the volume expansion of the active material is reduced.
