A Ni / METAL HYDRIDE BATTERY OF BIPOLAR STACK DESIGN

Application IN/PCT/2002/00022/MUM published 2006-09-15, filed 2002-01-07
The invention relates to a battery in bipolar stacked configuration comprising a plurality of subcells which are accommodated in a container that is closed in a gas-tight manner. The subcells each consist of two electrodes of different polarities and of an electrolyte-impregnated separator and are electronically connected via a sandwiched electrically conductive connecting wall. All subcells are connected to a common gas space. The connecting walls between the subcells provide the electrical contact and simultaneously exclude any electrolytic connection. The electrolyte is stipulated in a limited quantity in the electrodes and the separator. The subcells are pressed together by a constant dynamic effect. The derivation is effected on the outer walls of the container which are configured as pressure plates. Each of the negative electrodes can have a higher capacity than that of the positive electrode belonging thereto. Drawing: 01 sheet. Total Pages: 15 (FIG.-02)
