Development of rechargeable monopolar and bipolar zinc/air batteries

For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in monopolar zinc/air cells. In addn., a bipolar Zn/air 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 differences in porosity of the zinc electrode before and after the long-term test were analyzed using mercury porosimetry. [on SciFinder (R)]
