PERFORMANCE AND USE OF COMPOSITE-SUBSTRATE-BASED BIPOLAR LEAD ACID BATTERIES FOR PULSED-POWER APPLICATIONS/

A new type of composite substrate is proposed for constructing fast di scharge bipolar lead/acid batteries. This newly developed substrate, u sed for constructing 4 V bipolar lead/acid batteries, displays no corr osion and a very low catalytic effect for both hydrogen and oxygen evo lution. The specific resistance is 1.2 Ohm cm while the areal resistan ce is 0.04 Ohm cm(2). The active layers are formed by the Plante forma tion method, both in situ and ex situ. For pulsed-power applications, where energy is quickly transferred to an inductor, a model calculatio n is given for deriving the required ratio of the specific power and t he specific energy.
