From: Selection of oxygen reduction catalysts for secondary tri-electrode zinc–air batteries
Galvanostatic cycling performance of oxygen electrodes MnOx + Ni-Fe-Co(OH)2 in a tri-electrode Zn–air set-up over 50 h at 20 mA cm−2 with 30 min cycle periods, in static electrolyte 4 M NaOH + 0.3 M ZnO at 333 K. Compressed air was supplied at 200 cm3 min−1.
