Highly durable and active non-precious air cathode catalyst for zinc air battery

The optimum composition of cathode catalyst has been studied for rechargeable zinc air battery application. La0.9Ca0.1Co1−xFexO3 (x=0–0.4)perovskite powders were prepared using the citrate method. The substitution ratio of Co2+with Fe3+cations was controlled in the range of 0–0.4. The optimum substitution ratio of Fe3+cations was determined by electrochemical measurement of the air cathode composed of the catalyst, polytetrafluoroethylene (PTFE) binder, and Vulcan XC-72 carbon. The substitution by Fe enhanced the electrochemical performances of the catalysts. Considering oxygen reduction/evolution reactions and cyclability, we achieved optimum substitution level ofx=0.1in La0.9Ca0.1Co1−xFexO3.

In this paper, we present analysis of air cathode performance, taking into account both electrode passivation and transport resistance raised by insoluble products. Both effects are theoretically evaluated and compared. Validation is carried out against experimental data under low currents. The effects of electrode pore structure, such as porosity and tortuosity, on both the influence of insoluble precipitates and discharge capability are investigated.
