Investigation of FeB alloy prepared by an electric arc method and used as the anode material for alkaline secondary batteries

High active FeB alloy was prepared by an electric arc method, and used as the anode material for alkaline secondary batteries. The structural characteristics of the as-prepared FeB alloy were studied using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), and the electrochemical performances were investigated using cyclic voltammetry (CV) and charge–discharge test. The FeB alloy achieves an excellent reversible capacity of 312 mA h/g as well as a good cycleability, and is proved to be a promising low-cost and high performance anode material for alkaline secondary batteries.
