- at an overpotential of 100 mV and low overpotentials at current densities of 333 μA·cm−2 were found for all electrodes made from cobalt-decorated fibre mats carbonised at temperatures between 800 and 1000 °C. Keywords: carbon fibres; cobalt-decorated fibres; electrospinning; metal–air batteries
- overall performance [3]. The lack of discharge performance is attributed to the sluggish kinetics of the oxygen reduction reaction (ORR) at the air cathode [4], which reduces the practical power density. Further improvements of the cathode are essential for the long-term success of metal–air batteries

- , constant, on-demand, and reliable manner [3][4][5][6]. Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) play critical roles in many clean energy storage and conversion devices (e.g., hydrogen produced from water splitting via water electrolyzers, hydrogen fuel cells, and metal–air
- batteries [7][8][9][10]). In order to meet the requirements for efficient catalysts in practical applications, platinum group metal (PGM)-based catalysts are currently used as principal catalysts to reduce the overpotential of ORR and OER due to their slow kinetics [11][12][13]. The high cost, poor

- expectations. A new and promising concept is to add soluble and redox-active molecules to the liquid electrolyte. In 2011 Liox Power Inc. filed a patent application on such “soluble oxygen evolving catalysts for rechargeable metal–air batteries” [96]. Those often called redox mediators (RM) molecules possess a
- ORR/OER reactions in metal–air batteries is not sufficient as also plating/stripping of the alkali metal needs to be reversible in order to achieve a long cycle life. Cell discharge using this IL based electrolyte at 25 µA/cm2 was characterized by a sloping decrease, charging (250 µA/cm2) mainly
