摘要
用水热法制备了氢氧化镍超级电容器电极材料,在对它的形貌、充放电电流等进行测试分析的基础上,应用速度反应理论,得到材料的充电电流强度和储能量与材料性质和充电时间等的关系.结果表明:材料的充电电流强度和储能量均随充电时间的增长而非线性地增大,其变化情况与反应物和生成物的化学势以及温度有关.理论与实验结果基本符合.
A nickel hydroxide electrode material for super-capacitors was prepared by the hydrothermal method.Based on the tests of its morphology and charge and discharge current,the authors of this paper analyzed the relationship of charging current strength and storage energy with the properties of the material and charging time according to the velocity response theory.The results showed that the charge current intensity and energy storage of the material increased nonlinearly with the increase of charging time and that the change was related to the chemical potentials of the reactant and the product and temperature.The theoretical results were proved to be consistent with the experimental results.
