Development of the zinc-chloride battery for utility applications. Work period: April 1, 1978-March 31, 1980. [Contains glossary]
Significant accomplishments in the research and development programs during Phase II of the Zn/Cl/sub 2/ battery development project were as follows: development of a data base on the density, conductivity, viscosity, chlorine solubility, and the zinc transference number for ZnCl/sub 2/-KCl-NaCl electrolytes; development of a model describing the hydrodynamic phenomena occurring between individual zinc and chlorine electrodes during charge; demonstration of cell electrochemical energy efficiencies of 74% for delivered capacity densities of 500 Wh/cm/sup 2/; completion of reliability studies for 100-MWh battery plants that discuss quantitatively plant availability and electricity cost in terms of module-failure rate; invention of a module-bypass switch concept that isolates a failed module in a series-connected string and thereby avoids string outage; development of a computer model for module operation that allows prediction of the effects of component changes on module performance; and accumulation of 1250 cycles - 50% of the target for battery-stack life - on a 1.7-kWh system with negligible performance degradation. 294 figures, 99 tables.
