| 中文摘要 | the microstructure and electrochemical hydrogen storage characteristics of la(0.67)mg(0.33-x)ca(x) ni(2.75)co(0.25) (x = 0, 0.05, 0.10 and 0.15) alloys are investigated. the results show that all alloys mainly consist of (la, mg)ni(3) and lani(5) phases, besides a small amount of (la, mg)(2)ni(7) phase. the cycle stability (s(80)) after 80 charge/discharge cycles of all alloy electrodes first increases from 60.1% (x = 0) to 64.2% (x = 0.05), then decreases to 45.9% (x = 0.15). the high rate dischargeability of all alloy electrodes first increases from 52.6% (x = 0) to 61.4% (x = 0.10), then decreases to 57.2% (x = 0.15). moreover, the charge-transfer resistance (12) first decreases from 168.2 m omega (x = 0) to 125.7 m omega (x = 0.10), then increases to 136.6 m omega (x = 0.15). all the results indicate that the substitution of mg with a certain amount of ca can improve the overall electrochemical characteristics.
