NI-H2 BATTERY HAVING IMPROVED THERMAL PROPERTIES

摘要

A common pressure vessel type nickel-hydrogen storage battery having an outer pr essure vessel (5) contains a stack of compartments. Each compartment includes at least one battery cell (80), a heat transfer member (21) and a cell spacer (22) for maintaining a relatively constant distance between adjacent compartments. Each heat transfer member inclu des a fin portion (21a), which is thermal contact with a battery cell, and a flange portion (21b) 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 ge nerated by the cell radially outward to the pressure vessel, which is capable of dissipating the heat into the surrounding atmosphere.
