高活性氢氧化亚镍制备——烘干温度对其活性的影响

The Preparation of High Activity Nickel Hydroxide The Influence of Drying Temperature on the Activity of Nickel Hydroxide

采用新型反应方法制备高活性氢氧化亚镍,并对其电化学活性与烘干温度的相互关系作了初步探讨。实验表明,随着温度的增加,氢氧化亚镍的电化学活性分别在50℃和130℃左右出现峰值,低温烘干时,Ni(OH)_2的电化学活性基本不受温度影响;高温烘干,温度的影响作用显著增强。

High activity nickel hydroxide was prepared with a new method in order to obtain maximum discharge capacity for the positive plastic-bonded electrode of nickel cadmium alkaline accummula-tors. The influence of drying temperature on the electrochemical activity of nickel hydroxide was discussed. Experiment showed that this nickel hydroxide had the maximum discharge capacity at 50℃ and 130℃ drying temperature. Higher drying temperature had a great influence upon the activity of nickel hydroxide and lower dryi...
