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

Electrochemical kinetic performances of electroplating Co–Ni on La–Mg–Ni-based hydrogen storage alloys

“…HF+KF aqueous solution helped to form protective and electro-catalytic layer on the surface, and thereby improved kinetic properties and cycling life [14]. Microencapsulations of alloy powders with Ni-P, Pd, Cu, Co coatings were devoted to improving the catalytic activity and the high-rate dischargeability [5,10,[15][16][17][18][19]. Up to now, most of studies on surface coating were focused single metal layer.…”

Electrochemical kinetic properties of AB5-type hydrogen storage alloys with chemically deposited polypyrrole

“…Rare earth-based AB 5 -type alloys, the most commercial negative materials, have been extensively investigated; however, the main drawback of the AB 5 -type alloys is the poor performance of significant deterioration in practical applications [3]. Many efforts, such as optimization of the alloy compositions, acid treatment, alkali treatment, and microencapsulation with Ni, Cu, Pd, etc.…”

“…Many efforts, such as optimization of the alloy compositions, acid treatment, alkali treatment, and microencapsulation with Ni, Cu, Pd, etc. [4][5][6][7][8], have been made to overcome the above shortcomings and hence to improve the comprehensive electrochemical performance. Surface modification by encapsulation with conducting polymer overlayer is one of the most efficient solutions, which can catalyze the dissociative chemisorption and associative desorption of H and improves the catalytic activity of the surface [9].…”

Ag-modification improving the electrochemical performance of ZnO anode for Ni/Zn secondary batteries

“…The surface modification has been widely * Corresponding author. investigated and adopted to improve the electrochemical performance of lithium-ion batteries [11][12][13][14][15][16][17], Ni/MH batteries [18][19][20][21][22], etc. For the surface-modified electrode materials, the corresponding products always present better electrochemical performance than the unmodified ones.…”
