摘要：
The amorphous nanometer Ni(OH)(2) was synthesized by quick cryoprecipatation. The effects of PH, temperature, surfactant etc on the characteristics of the sample powder were discussed. The results show that the sample powder is amorphous with about 30 nm grain size and its morphology is similar to the spherical when PH value is 11 similar to 12, the temperature is 55 degrees C and the surfactant is Tween-80. A simulated MH-Ni battery was assembled with amorphous Ni(OH)(2) as positive activity material nickel, the experimental results show that it has lower charge voltage, lower AC-impedance, longer discharge time, and.discharge voltage smoothed at 1.258 V, and its discharge specific capacity reaches 349.85 mAh/g.
