摘要:
An assembled storage battery unit of the collective type includes a plurality of storage batteries assembled as a unit. The storage batteries each include positive and negative electrodes layered through a separator and contained in a bottomed parallelepiped battery casing filled with electrolyte and a closure plate welded to an upper opening end of the battery casing to seal the interior of the battery casing. The battery casings each are integrally formed with a plurality of vertical ribs spaced in parallel at one side wall thereof faced to the corresponding side wall of the battery casing adjacent thereto. The vertical ribs of each of the battery casings are coupled with the corresponding vertical ribs of the battery casing adjacent thereto to form a plurality of vertical ventilation spaces.

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.

摘要:
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.
