Electrochemical Studies of Zinc Electrode for Rechargeable Zinc-Air Systems

This article aims at improving the zinc electrode in terms of mechanical strength and number of cycles. An optimization of the ratio ZnO/Zn and the current collector was performed. For its evaluation impedance spectroscopy was used. The obtained results show improvement of the charge/discharge cycling in comparison with the non-optimized Zn-electrode. For the first 200 cycles the system operates without capacity change. For 800 cycles the capacity decreases with 30 %.
