A stationary electric power system including a low profile secondary battery that includes a battery body including an electric power generating element accommodated in an exterior package member. The low profile secondary battery includes a spacer disposed between the battery body and other battery body when the other battery body is stacked on the battery body. The spacer fixes the battery body in a predetermined position. The battery body and the spacer are connected with each other through an elastic body.

Stationary electric power system and method for manufacturing stationary electric power system including battery body and spacer

Within outer cover memberof laminated film including resin layer, there is installed electricity generating elementthereby to constitute battery body, peripheral portionof the outer cover member being sealed. Spaceris provided which has fixing portionby which the battery body is fixed to predetermined position, the spacer being arranged between outer peripheral portion of the battery body and outer peripheral portion of another battery body put on the battery body. In range Hthat includes an overlapped portionbetween the outer peripheral portion and the spacer and is provided at least around the fixing portion of the outer peripheral portion, there is provided elastic resin portionproduced through insert molding of elastic resin. This thin battery exhibits satisfied stability in set condition against vibration of motor vehicle. This thin battery exhibits satisfied fixing stability against vehicle vibration.

Thin battery

A sealed nickel-metal hydride storage cell includes a positive electrode containing nickel as a positive electrode active material, a negative electrode containing a hydrogen-absorbing alloy as a negative electrode active material, a separator interposed between the positive electrode and the negative electrode and an electrolyte immersing therein the positive electrode and the negative electrode. The negative electrode has a theoretical capacity larger than a theoretical capacity of the positive electrode so as to provide a charge reserve capacity when the positive electrode is in a fully charged state and to provide a discharge reserve capacity when the positive electrode is in a fully discharged state. A ratio of the charge reserve capacity to the discharge reserve capacity ranges from 1:0 to 1:0.5.
