ELECTRICAL STORAGE DEVICE, MANUFACTURING METHOD OF THE SAME, AND SEPARATOR

摘要

An electrical storage device includes an electrical storage element and an electrolytic solution. The electrical storage element is formed of an anode body, a cathode body facing the anode body, and a separator interposed between the anode body and the cathode body. The separator includes a separator substrate and a conductive polymer adhering to the separator substrate. The electrical storage element is impregnated with the electrolytic solution. The separator includes a first surface layer having a first surface facing the anode body and a second surface layer having a second surface facing the cathode body. The first surface layer includes a first region that is not provided with the conductive polymer, and the second surface layer includes a second region provided with the conductive polymer.
