anode material was prepared by melting and casting with the protection of Ar. The effects of additive elements on performance of Al alloy anode were studied by orthogonal test. The phase structure, morphology and composition distribution of Al alloy were investigated by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The electrochemical......
