混合电解液中贮氢电极性能的研究

Study of the Properties of Hydrogen Storage Electrode in Mixed Electrolyte Solution

测定了 MlNi_(3.5)MnCo_(0.4)Al_(0.1)(Mi:富镧混合稀土金属)贮氢电极在 KOH+NaOH 混合电解液中的性能。结果表明,在 KOH 电解液中掺入少量的 NaOH,能提高电极的充放电效率、降低放电过电位,但使电极的循环充放性能有所下降;同时 NaOH 含量不同对电极的快速放电能力以及电荷保持能力的影响也不同。

The properties of MlNi_(3.5) MnCo_(0.4) A1(0.1) (Ml:La-rich misehmetal) hydrogen strorage electrode in mixed electrolyte solution are studied.The results have shown that the electrode had higher charge efficiency and lower discharge overpotentials in mixed electrolyte solution.The fast discharge ability and charge retention ability of the electrode are changed with NaOH contents in eleetrolyte solution.
