| 中文摘要 | structure and electrochemical characteristics of la0.96ce0.04mg0.15al0.05ni2.8 hydrogen storage alloy have been investigated. x-ray diffraction analyses reveal that the la0.96ce0.04mg0.15al0.05ni2.8 hydrogen storage alloy consisted of a (la, mg)ni-3 phase with the rhombohedral puni3-type structure and a lani5 phase with the hexagonal cacu5-type structure. tem shows that the alloy is multicrystal with a lattice space 0.187 nm. eds analyse shows that the content of mg is 3.48% (atom) which coincide well with the designed composition of the electrode alloy. electrochemical investigations show that the maximum discharge capacity of the alloy electrode is 325 mah g(-1). the alloy electrode has higher discharge capacity within the discharge current density span from 60 ma g(-1) to 300 ma g(-1). electrochemical impedance spectroscopy measurements indicate that the charge transfer resistance.. t on the alloy electrode surface and the calculated exchange current density i-0 are 0.135 omega and 1298 ma g(-1), respectively; the better eletrochemical reaction kinetic of the alloy electrode may be responsible for the better high-rate dischargeability. |
