摘要: Abstract To identify an adequate material for Fe/air battery anodes, we used pure α-Fe2O3 with 1–10 μm grain size as active to comparison commercial materials. Highly relative homogeneous micro mainly rhombohedral-like shape was prepared by a controlled synthesis method. The effect of morphology, shape, and particle Fe2O3 on the electrochemical behavior Fe2O3/AB electrode investigated using X-ray diffraction, scanning electron microscopy coupled energy-dispersive spectroscopy, transmission microscopy, cyclic voltammetry, galvanostatic cycling performance. Results showed that provided shaper redox peaks deposition were separate from hydrogen evolution. In initial cycles, both nanoparticles microparticles yielded similar discharge capacities but prolonged higher capacities.
