摘要: Effects of metal oxide additions on the electrochemical hydriding and dehydriding behavior Mg2Ni-type hydrogen storage alloy in 6 M KOH aqueous solution were investigated. The electrode characteristics mechanically alloyed composites Mg1.9Y0.1Ni0.9Al0.1–5 wt% MO (MO=Ag2O, Fe2O3, MoO3, RuO2 V2O5) examined such as discharge capacity, high-rate dischargability cycle life. capacity greatly increased by modification with additions, but life decreased. performances characterized using both dc polarization ac impedance analysis techniques. diffusivity alloys was estimated an method.
