ABSTRACT:
A common pressure vessel type Ni--H.sub.2 storage battery having an outer pressure vessel that contains a stack of compartments. Each of the compartments including at least one battery cell, a heat transfer member, and a cell spacer for maintaining a relatively constant distance between adjacent compartments. The heat transfer members include a fin portion, which is in thermal contact with the battery cell, and a flange portion which extends longitudinally from the fin portion and is in tight thermal contact with the inner wall of the pressure vessel. The heat transfer member serves to transfer heat generated from a battery cell radially outward to the pressure vessel, which is capable of dissipating the heat into the surrounding atmosphere.
