Abstract

The environmentally friendly and safe zinc/air redox flow battery offers a possible solution to overcome irregular electricity fluctuations caused by wind and solar power systems. However, stability issues regarding Zn deposition and air electrode cyclability still limit their implementation as energy storage system into our electricity grid. In this work air electrodes catalyzed with La0.6Ca0.4CoO3 perovskite supported on Ni foam and Ni cloth respectively were manufactured and electrochemically characterized. The electrodes show good performance with regard to the charging reaction i.e. oxygen evolution reaction, however, further experiments concerning the oxygen reduction during discharge need to be performed.
