Hydrides of Laves type Ti–Zr alloys with enhanced H storage capacity as advanced metal hydride battery anodes
Wijayanti, Ika Dewi; Denys, Roman Volodymyrovich; Suwarno, Suwarno; Volodin, Alexei A.; Lototskyy, Mykhaylo V.; Guzik, Matylda N.; Nei, Jean; Young, Kwo; Roven, Hans Jørgen; Yartys, Volodymyr (Peer reviewed; Journal article, 2020)The present work was focused on the studies of the effect of variation of stoichiometric composition of Ti–Zr based AB2±x Laves phase alloys by changing the ratio between A (Ti + Zr) and B (Mn + V + Fe + Ni) components ... -
Novel Zr- based AB2 Laves type Alloys as Advanced Anodes for High Energy - High Power Metal Hydride Batteries
Wijayanti, Ika Dewi (Doctoral theses at NTNU;2020:129, Doctoral thesis, 2020)Metal hydrides have been studied during the last five decades as efficient materials for various energy storage and conversion systems. Among applications, the use of metal hydrides as electrode materials is the most ... -
Studies of the effect of melt spinning on the electrochemical properties of the AB2 Laves phase alloys
Wijayanti, Ika Dewi; Mølmen, Live; Denys, Roman Volodymyrovich; Guzik, Matylda Natalia; Gorsse, Stéphane; Yartys, Volodymyr (Peer reviewed; Journal article, 2021)A comparative study of the effect of melt spinning on the electrochemical properties of the C14 and C15 AB2 alloys has been performed. The wheel speeds of 630, 2100, and 4100 cm/s were applied during the rapid solidification ... -
