New generation of rechargeable zinc-air batteries

For the development of an elec. rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in a monopolar zinc/oxygen cell. In addn., a bipolar Zn/oxygen stack was tested using reticulated copper foam as substrate for the zinc deposit. The cells were cycled in moderately alk. ZnO-satd. electrolytes with KF as an electrolyte additive. The max. power as well as the cycle life of the cells was investigated. The microstructure and the performance of the electrodes before and after cycling were studied exptl. using phys. (mercury porosimetry), electrochem. and imaging (x-ray photog.) techniques.
