摘要 Nd-Al codoped amorphous nickel hydroxide powders were synthesized by microemulsion precipitation method combined with rapid freezing technique.The microstructure of the prepared samples was analyzed with X-ray diffractometer(XRD),scanning electron microscopy(SEM),and Raman spectroscopy.The electrochemical performances of the prepared samples were characterized with charge/discharge test,cyclic voltammetry,and electrochemical impedance spectra.The results showed that the codoping of Nd-Al resulted in more st...
