Bipolar lead acid batteries: effect of membrane conductivity on performance

Bipolar lead/acid batteries offer the possibility of increased energy and p ower density. This paper presents the results of a theoretical and experime ntal study into the performance of a bipolar construction. A model that cal culates the ohmic losses in a bipolar lead acid battery has been used to pr edict the cell voltage during discharge. The calculated discharge curves ar e in good agreement with experimental results obtained with a 6 V lead memb rane bipolar prototype. In a second part the conductivity of the bipolar pl ates have bean adjusted in the program to estimate its influence on battery performance. (C) 1999 Elsevier Science S.A. All rights reserved.
