Abstract
In an electric storage device, lithium electrodes are disposed on respective outermost portions of an electrode laminated unit in which a positive electrode and a negative electrode are laminated alternately via positive/negative electrode separators. The lithium electrode includes lithium metal serving as a lithium ion supply source, and a lithium electrode separator (a non-woven fabric separator) constituted by a non-woven fabric that satisfies the following conditions: (a) an average fiber diameter of 0.1 μm to 10 μm; and (b) a thickness of 5 μm to 500 μm is provided. By forming the lithium electrode separator that contacts the lithium electrode including the lithium ion supply source from a non-woven fabric in this manner, a dramatic improvement can be achieved in the cycle characteristic of the electric storage device.
