Influence of tin on the electrochemical and gas phase hydrogen sorption in Mg2−xSnxNi (x=0, 0.1, 0.3)

Influence of boron on the hydriding of nanocrystalline Mg2Ni

“…It can be concluded that the amount of absorbed hydrogen decreases immediately after the first cycle. Both alloys show comparable corrosion stability, substantially lower than that of pure Mg 2 Ni [26]. Although the alloy with lower B content reveals slightly better electrochemical hydrogen charge/discharge behavior compared to the B richer alloy the discharge capacity and cycle life as a whole are rather low and unsatisfactory.…”

“…7 for both alloys. The B containing Mg 2 Ni alloys show however worse electrochemical hydrogen storage properties in comparison with the pure intermetallic compound [26].…”

Electrochemical hydrogen-storage performance of Mg20−x Y x Ni10 (x = 0–4) alloys prepared by mechanical milling

“…Mechanical milling is a highly appropriate technique for producing amorphous and nanocrystalline Mg 2 Ni alloys with different compositions. Drenchev et al [13] synthesized Mg 2-x Sn x Ni (x = 0, 0.1, 0.3) alloys with the average grain sizes ranging from 3 to 7 nm by means of reactive ball milling. However, these compounds showed the highest discharge capacity of only about 300 mAh g -1 , which declined to below 50 mAh g -1 after five charging and discharging cycles.…”

Consumption reduction of AB5 alloy in Ni–MH battery by the use of cobalt oxyhydroxide coated nickel hydroxide

“…It has a specific capacity about 300-320 mAh/g and is appreciably expensive as cobalt metal is contained. Now the research focus on two aspects: one is to develop hydrogen absorbing alloys with higher capacity and lower price, such as Mg-Ni alloy [1][2], the other is to lower the content of cobalt in AB 5 alloy [3][4]. But till now, these new alloys can hardly meet the requirements of industrial production because of their poor life performance.…”
