A Zinc Paste Primary Battery
Abstract
It is pointed out that zinc/air batteries could, in principle, be used to power electric vehicles. One concept for enhancing the practical performance of this battery system involves the separation of energy density factors from power density factors. This concept can be implemented by employing the active negative plate material in the form of a zinc slurry, which is circulated from a reservoir through the negative electrode compartment. An extension of this fuel cell-battery concept is related to the utilization of the active material as a pumpable paste rather than as a slurry. The present investigation is concerned with preliminary experiments on formulating and characterizing pumpable zinc/zinc oxide pastes in the context of a primary zinc/oxygen battery. A 'paste' is defined as a thick viscous mass of solid, uniformly and semipermanently dispersed in a liquid phase. Attention is given to the physical basis for predicting which solid/liquid mixtures will provide pumpable pastes.
