    摘要:

    研究了表面包覆Ni-P對(duì)PuNi3型貯氫合金La0.67Mg0.33Ni2.5Co0.5電極的電化學(xué)性能的影響.結(jié)果表明包覆鎳處理改善了貯氫合金電極的循環(huán)穩(wěn)定性.線性極化掃描和電化學(xué)阻抗譜等分析結(jié)果表明,包覆后合金電極的極限電流密度(I1),交換電流密度(I0)以及電化學(xué)阻抗均有較好的改善,說(shuō)明電荷轉(zhuǎn)移和氫的擴(kuò)散能力得到提高.經(jīng)25次電化學(xué)循環(huán)后的電極合金金相觀察和分析表明,包覆Ni-P處理沒(méi)有有效抑制其粉化,這與該類型貯氫合金電化學(xué)吸氫時(shí)氫化物膨脹較大有關(guān).

    Abstract:

    The effects of Ni-P coatings on the electrochemical properties of La0.67Mg0.33Ni2.5Co0.5 hydrogen storage alloy electrode was studied. The kinetic properties of the alloy electrode were evaluated. The results show that the cycling stability of the electrode is improved. The Ni-P coated powder electrode is better than bare electrode in exchange current density I0, Limiting current density I1, high rate dischargeability and hydrogen diffusion coefficient D. It is found that the surface microencapsulation is ineffective in prohibiting disintegration, main reason for which is probably ascribed to the larger expansion of the La0.67Mg0.33Ni2.5Co0.5 hydrogen storage alloy hydride.
