Influence of addition of Cu(OH)2 to KOH alkaline electrolyte on electrochemical properties of La2Mg0.9Al0.1Ni7.5Co1.5 hydrogen storage alloy electrode WANG Da-hui(王大辉)1, LUO Yong-chun(罗永春)2, YAN...: The influence of the addition of Cu(OH)2 to 6 mol/L KOH alkaline electrolyte on the electrochemical properties of La2Mg0.9Al0.1Ni7.5Co1.5 hydrogen storage alloy electrode was investigated by electron probe X......
performances of hydrogen-storage alloy electrodes, Mm0.3Ml0.7Ni3.55Co0.75Mn0.4-Al0.3-x%Mg2Ni (x=0,5,10,30) composite hydrogen storage alloys prepared by two-step re-melting were investigated in this work.... With the increasing of x value, capacity retentions of the composite hydrogen storage alloys rise from 66.21% while x=0 to 82.04% while x=10, but the capacity retention of the composite alloy with 30% Mg2Ni declines......
Influence of annealing temperature on electrochemical properties of rapidly quenched LPC(NiAlMn)4.25Co0.75 hydrogen storage alloy electrodes ZHENG Qun(郑 群), CHEN Yun-gui(陈云贵), WANG Jin-guo(王金国.... The annealing treatments make cell volume increase, dislocations and strain decrease, and the distribution of alloy composition become homogeneous. Key words: LPC mischmetal; hydrogen storage......
