In hybrid electric vehicles (HEV) the requirements on batteries are very different from those for battery electric vehicles (BEV). A high power (bipolar) lead-acid battery could be a good alternative for other types of batteries under development for this application. It is potentially cheap and there is an established recycling infrastructure. At TNO work started somewhat more than 5 years ago on the development of a bipolar lead-acid battery for pulse power applications. The last two years TNO, in cooperation with the Centurion, a Dutch lead-acid battery manufacturer, worked on the improvement of this type of battery, with respect to specific power (and energy) and other relevant properties. Beside a number of laboratory test cells, two succeeding prototypes of 80 V modules have been built and tested with simulated HEV drive cycles. For the second prototype, a specific power of about 500 W/kg was obtained, a doubling in comparison to the first prototype. On the basis of the results, an evaluation has been made to come to a design which can be mass produced at acceptable cost.
