Electrochemical properties of Ti45Zr38−xNi17+x (0 ≤ x ≤ 8) quasicrystals produced by rapid-quenching

▶ Discharge performances of Ti45Zr38-xNi17+x (0≤x ≤8) icosahedral quasicrystal ribbons produced by rapid-quenching were measured by a three-electrode cell at room temperature. ▶ The maximum discharge capacity achieved was about 90 mAh/g from (Ti45Zr30Ni25) ribbon with no formation of metal hydride.
