| 英文摘要 | The AB(5)-type alloy powder (MINi3.6Co0.7Mn0.3Al0.4) prepared by melt-spinning was treated by a reducer (solution of sodium hypophosphite) to form a Ni-rich layer on the surface of the particles, which can obviously improved the activity of the quenched powder. For the treated alloy powder the discharge capacity after 2 cycles of charge-discharge reached an ideal value of 241 mA(.)h(.)g(-1), but only 222 mA(.)h(.)g(-1) for the non-treated alloy powder after 5 cycles of charge-discharge. AES and XPS results show that the nature of the oxide layer formed on the surface plays a key role on the activation process of the metal hydrides in alkaline solution. |
