Patent ID: 8530083

Claim:
An electric storage device which includes plural electrodes and plural ion-conductive layers that are stacked such that each of the plural ion-conductive layers is disposed between a pair of electrodes among the plural electrodes, wherein: each of the plural electrodes includes a current collector, and an electrode layer, formed on the current collector, which contains an active material; a first electrode among the plural electrodes is disposed in a position where heat radiation performance is lower than the heat radiation performance in a position where a second electrode among the plural electrodes is disposed, in a stacking direction in which the plural electrodes are stacked in the electric storage device; a configuration of the electrode layer in the first electrode differs from a configuration of the electrode layer in the second electrode such that a resistance value in the first electrode is larger than the resistance value in the second electrode; the first electrode is positioned in a center portion of the electric storage device in the stacking direction; and the second electrode is closer to an end of the electric storage device in the stacking direction than the first electrode.
