Abstract
The positive electrode active materials of Ni(OH)2 powders for alkaline Ni-MH
battery have been fabricated by a chemical precipitation method. 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.
