Abstract:

Results from an experimental study pertaining to the development of a high energy density seawater battery are presented. In the initial phase of the study, cell orientation, cell geometry, electrode structure, and salinity effects were examined as to their effects on the current versus time characteristics and the electromotive force. In the second phase, injection of nonreacting nitrogen and reacting oxygen and chlorine gases through the porous cathodes was investigated. Nitrogen had only a slight effect on increasing cell performance. Battery reaction mechanisms are discussed from an inductive viewpoint based on the Nernst equation and also from the theory of charge transport in ionic solutions. The feasibility of employing the chlorine seawater battery for underwater applications is also discussed.
