Abstract: A laminated power storage element includes: an exterior body shaped into a flat bag shape by laminating a pair of laminated films to weld a peripheral edge region; an electrode body sealed within the exterior body; a positive and a negative electrode terminal portion allowed to project outside the exterior body from a predetermined margin of the exterior body; and a pair of tab films welded on surfaces where the pair of laminated films oppose one another in a region along the predetermined margin to mutually weld the pair of laminated films, and the tab film covers an end surface of the laminated film while deviating outward from the exterior body from the predetermined margin, and covers both front and back surfaces of each of a base end of the positive electrode terminal portion and a base end of the negative electrode terminal portion.

Abstract: A laminate-type power storage element has a flat body and an interior layered flat plate-shaped electrode body. A positive electrode terminal plate is mounted to a positive electrode of the electrode body and is guided outside from a predetermined margin of the body. A negative electrode terminal plate is mounted to a negative electrode of the electrode body and guided in the same direction. A film member spans across both electrode terminal plates. The film member is made by layering an insulating heat-resistant film and an adhesive to thermocompression bond the heat-resistant film to a matter to be adhered to. The film member is thermocompression bonded to the electrode terminal plate at a region facing principal surfaces of the positive and the negative plates, and is thermocompression bondable to the matter to be adhered to in a region that does not face the respective principal surfaces.

Abstract: A charge control method for an alkaline storage battery includes determining whether or not a temperature T of a battery is less than 0° C.; if the temperature T is equal to or higher than 0° C., determining whether or not the battery has been considered to be charged to a maximum capacity that can be stored in the battery; if the battery has not been considered to be charged to the maximum capacity, determining the temperature T of the battery again; if the battery has been considered to be charged to the maximum capacity, finishing the charging; if it is determined that the temperature T is less than 0° C., determining whether or not a specified voltage value has been reached, the specified voltage value having been preset in a range lower than a voltage value when the battery has been considered to be charged to the maximum capacity that can be stored in the battery; if the voltage value of the battery has not reached the specified voltage value, determining the temperature T of the battery again; and if the voltage value of the battery has reached the specified voltage value, finishing the charging.

Abstract: A nickel hydrogen secondary battery 2 has an outer can 10, and an electrode group 22 accommodated together with an alkali electrolyte solution in the outer can 10. The electrode group 22 includes a positive electrode 24 and a negative electrode 26 stacked through a separator 28. The positive electrode 24 includes a first positive electrode active substance and a second positive electrode active substance. These first and second positive electrode active substances each contain nickel hydroxide as a main component, and the first positive electrode active substance and the second positive electrode active substance differ in the amount of magnesium solid-dissolved.

Abstract: A laminate-type power storage element includes a flat plate-shaped electrode body and an exterior body. The electrode body is configured by stacking a sheet-shaped positive electrode and a sheet-shaped negative electrode on either side of a separator. The exterior body is formed in a flattened bag-shape by thermocompression bonding peripheral edge regions of two opposing laminated films, to seal the electrode body inside the flattened bag-shape of the exterior body together with an electrolyte. The separator has a sheet-shaped substrate and at least one bonding layer formed on at least one surface of the substrate. A peripheral edge portion of the separator is sandwiched between and bonded by the two laminated films at a peripheral inside of the peripheral edge regions of the two laminated films.
