Abstract
A positive electrode sheet including a positive electrode mixture layer formed on one surface is provided at one of the outermost layers of an electrode sheet group, while a positive electrode sheet including a positive electrode mixture layer formed at one surface is provided at the other outermost layer of the electrode sheet group. A negative electrode sheet including negative electrode mixture layers formed on both surfaces is provided between the positive electrode sheets. A lithium electrode sheet including metal lithium foils formed on both surfaces is overlapped onto the electrode sheet group formed by stacking the three sheets. When a wound-type electric storage device is produced, the electrode sheet group is wound together with the lithium electrode sheet.
