| 中文摘要 | the microstructure and electrochemical hydrogen storage characteristics of la(0.7)mg(0.3-x)ca(x)ni(2.8)co(0.5) (x = 0, 0.05 and 0.10) alloys prepared by arc-melting and subsequent powder sintering method are investigated. the electrochemical measurement results show that the cycle stability after 100 charge/discharge cycles first increases from 46.4% (x = 0) to 54.3% (x = 0.05), then decreases to 43.2% (x = 0.10), and the high rate dischargeability increases from 64.5% (x = 0) to 68.5% (x = 0.10) at the discharge current density of 1200 ma/g. the electrochemical impedance spectroscopy analysis indicates that the electrochemical kinetics of the alloy electrodes is improved by increasing ca. the entire results exhibit that a suitable content of ca (x = 0.05) can improve the overall electrochemical hydrogen storage characteristics of the alloys.
