Process for preparing an electrode for secondary battery employing hydrogen-storage alloy |
摘要 |
The present invention relates to a process for preparing an electrode for secondary battery employing hydrogen-storage alloy systems, more specifically, to a process for preparing an anode material for secondary battery which can be charged/discharged in an electrolyte and has a high discharge efficiency and energy density per unit weight, by sintering a mixture of hydrogen-storage alloy systems. An electrode for secondary battery of the present invention is prepared by the process which comprises the steps of: (i) mixing a hydrogen-storage alloy powder free of Ni with a hydrogen-storage alloy powder containing Ni over 30 atomic %; (ii) cold-pressing the mixed powder at a pressure of 5 to 15 ton/cm2; (iii) sintering the cold-pressed mixture in a quartz tube at 900 DEG C. for 5 to 15 min under a vacuum condition of 10-2 to 10-3 torr; and, (iv) quenching the sintered material.
