摘要：

Electrolytic impregnation of nickel hydroxide into porous sintered nickel plaque from nickel nitrate solutions was carried out at various current densities under room or high temperatures. The morphology of the deposited surface was observed with an electron microscope and the surface products were analyzed by means of X-ray diffraction. The loading level of nickel hydroxide as active materials has attained 1.6 g cm(-3) void volume and the appearance of the electrode surface has the black bivalent nickel hydroxide. However, the amount of nickel hydroxide decreased with number of impregnation times, because the bath composition was not necessarily uniform. From the result of discharge capacity analysis, it was considered that the cell capacity was dependent on the surface morphology of active materials. (C) 1998 Elsevier Science S.A.
