包覆钯和镍后MmNi5基贮氢合金的电化学特性
Electrochemical Characteristics of MmNi5-Based Alloys Coated with Palladium and Nickel
【摘要】 测定了包覆10wt%Pd-Ni后Mm0.9Ti0.1Ni3.9Mn0.4Co0.4Al0.3合金,及由其制成Ni-MH电池的电化学特性。包覆Pd—Ni的贮氢合金电极200次循环后容量仅衰减3%。负极为合金包覆Pd—Ni的Ni-MH电池在0.4C放电时的平均放电电压为1.27V。在3C放电时的放电容量为0.4C时的76%。
【Abstract】 Abstract: The electrochemical characteristics of Mm0.9Ti0.1Ni3.9Mn0.4Co0.4Al0.3 alloy coated with 10wt% palladium-nickel and the Ni-MH batteries have been examined. The capacity decay of Pd-Ni-coated alloy electrode is only 3% after 200’cycles. The average discharge voltage of battery using the Pd-Ni-coated alloy powder is 1.27V at 0.4 C rate and the discharge capacity at 3 C is 76% of the value at 0.4 C rate.
