Abstract

Surface-treated MmNi_3.55Co_0.75Mn_0.4Al_0.3 alloy as negative electrode material of nickel-metal hydride battery was employed to improve the high-rate dischargeability. Surface treatment was realized by dipping and stirring the alloy into a HCl aqueous solution with various concentrations at room temperature. The microstructure of the alloy before and after surface treatment was analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrochemical properties before and after surface treatment were comparedand the alloy treated in 0.025 mol/L HCl solution showed the optimal high-rate dischargeability.
