摘要
本文对在粘结式Ni(OH)_2电极中添加镍粉的放电容量、循环伏安行为以及充电后的结构变化进行了研究。结果表明镍粉在碱性溶液中过充电后有部分β-NiOOH的生成,因此在测试Ni(OH)_2放电容量过程中,采用过量镍粉时应扣除镍粉的容量贡献才是Ni(OH)_2的真正容量。
Studies were focused on discharging capacity .structural changes and voltammetric behavior of the nickel powder doped in paste - type Ni(OH)2 electrodes. The experimental results exhibited that the nickel powder would be oxidized into β-NiOOH during charging in alkaline solution so the obtained discharging capacity of the doped Ni(OH)2 electrode should include that increased by the formation of β-NiOOH from the nickel powder.
