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