Comparison of pretreatments by alkaline (Li, Na, K) hydroxides with NH3–H2O in the work function and hydriding kinetics of LaNi2.5Co2.5

Influence of electroless coatings of Cu, Ni–P and Co–P on MmNi3.25Al0.35Mn0.25Co0.66 alloy used as anodes in Ni–MH batteries

“…Hence, it is essential to increase the alloy's conductivity and the electrocatalytic activity so as to improve its performance. Various types of surface modifications [5][6][7][8][9] have been reported to improve the electrocatalytic nature of metal hydride electrodes. Surface modifications of metal hydride alloy particles by electroless plating with Cu, Ni-P, Ni-B, Pd and Co have shown improvement in cycle life and high rate capability [10][11][12][13]7].…”

Effects of ion irradiation on hydriding rate of Mm based hydrogen storage alloy

“…The dissociation of the H 2 or H 2 O molecule becomes markedly influenced by surface conditions of a metal. So far, we have systematically investigated the effect of surface oxide layers on the kinetics of hydrogen absorption by hydrogen absorbing metals [4,5] and reported several methods of surface modifications, such as metallic coatings [6], fluorination treatment [7,8] and alkaline treatment [9]. Using the ion beam, ion irradiation can effectively induce the formation of vacancies in the surface region of alloy.…”

Effects of surface modification by ion irradiation on the electrochemical hydrogen absorption rate of Pd

“…The dissociation of the H 2 or H 2 O molecule is markedly influenced by surface conditions of a metal. So far, we have systematically investigated the effect of surface oxide layers on the kinetics of hydrogen absorption by hydrogen absorbing metals [1,2] and reported several methods of surface modification such as metallic coating [3], fluorination treatment [4,5], and alkaline treatment [6].…”
