Review on Heterogeneous Electron Transfer in Graphene Electrode with Redox Couple

The development of Metal-Air Batteries MABs has been impeded by their poor rate capability and a lack of efficient and stable air catalysts, the former owing to the sluggish kinetics of the oxygen reduction reaction. Due to their high specific energy, low cost, and safety, Metal-Air Batteries (MABs), particularly rechargeable MABs, have reawakened attention as a viable energy storage/conversion solution
