Abstract
Mn-substituted nickel hydroxide with good electrochemical properties was prepared by mechanical ball milling and its preparation technology was studied. The optimization technology condition was Mnsubtituted 20%,ball milling time 15 min,ball material ratio 8:1,rotate speed 350 r/min and ageing temperature 70℃. The results of X-ray diffraction and scanning electronic microscope tests showed that it had a β-Ni(OH)2 structure with an irregular shape and the particle size was about 5 μm. Its 0.2 C discharge capacity reached 261 mAh/g and 1 C discharge capacity remained 90% after 300 cycles.
