The characteristic properties of Ni(OH)2 powders were analyzed by the XRD and SEM. The electrochemical properties of Ni(OH)2 powders were also analyzed by the galvanostatic charge-discharge test and AC impedance spectroscopy. In general, it must be noted that a nickel hydroxide electrode with the addition of cobalt hydroxide shows much better electrochemical properties. It was observed that the electrochemical properties of nickel cathodes depend on the contents of cobalt additive. It was indicated that the Ni-MH batteries have good performance of charge and discharge characteristics.application/pdf296855 bytesapplication/pdfzh-TW國立臺灣大學材料科學與工程學研究所氫氧化鎳化學共沉澱法鈷添加物Ni(OH)2chemical precipitation methodcobalt additivereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/12467/1/922216E002006.pdf
