An alkaline storage battery includes a plurality of foil electrodes that each have a metal foil and an active material layer. The active material layers are arranged in such a manner that adjacent two of the active material layers face each other. Separators which are each interposed between the adjacent two of the active material layers. The separators are each a nonwoven fabric including fibers as protruding portions. The active material layers have a large number of active material particles which adhere to each other, and spaces formed between the active material particles, as fitting portions. The fibers are engaged with the spaces while the fibers enter the spaces.

A power storage module includes a cylindrical resin portion that extends in a direction in which a plurality of bipolar electrodes is stacked and that accommodates therein the plurality of the bipolar electrodes. The resin portion includes a first seal portion that has a cylindrical shape and is joined to peripheral edge portions of a plurality of electrode plate, and a second seal portion that has a cylindrical shape and is disposed outside the first seal portion in a direction that crosses the stacking direction of the bipolar electrodes. A plurality of separators is disposed such that outer peripheral ends of the separators are located between an outer peripheral end of the first seal portion and an inner peripheral end of the first seal portion.

Power storage module

An electricity storage device includes an electrode assembly and a load applying mechanism. The load applying mechanism applies, to the electrode assembly, a load in a direction in which the positive electrode and the negative electrode are stacked in the electrode assembly. The negative electrode includes a metal foil and an active material layer that covers at least part of the metal foil and contains a carbon-based material as an active material. The density of the carbon-based material in the active material layer is 1.2 g/cmor higher. The degree of orientation that is defined as a ratio (I(100)/I(002)) of an X-ray diffraction intensity I(100) of a (100) plane to a diffraction intensity I(002) of a (002) plane in the active material layer is lower than or equal to 0.3. The load applied by the load applying mechanism is greater than or equal to 0.22 MPa.

Power storage device

A panel structure of a sun roof includes: a panel; an inner panel that is made of a metal plate, is provided below the panel to extend along an edge portion of the panel, and has a recessed portion that is recessed downward and a flange portion that spreads outward along the panel over an entire periphery of the recessed portion; a sealing member that is made of a resin molding material having a constant cross section, is interposed between the flange portion and the panel over an entire periphery of the flange portion, and is bonded to a lower surface of the panel and an upper surface of the flange portion; and a covering member that is made of a resin material, is fixed to the panel, and is provided to cover the inner panel and the sealing member.
