Development of rechargeable monopolar and bipolar zinc/air batteries

摘要: For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc were prepd. tested in monopolar cells. In addn., bipolar Zn/air stack was using reticulated copper foam as substrate for deposit. The cells cycled moderately alk. ZnO-satd. electrolytes with KF an electrolyte additive. max. power well cycle life investigated. differences porosity electrode before after long-term test analyzed mercury porosimetry.
