中文摘要	the (la0.67mg0.33)(1-x)tixni2.75co0.25 (x = 0, 0.05, 0.10, 0.15 and 0.20, at%) alloys were synthesized by arc melting and subsequent heat solid-liquid diffusing method. the structure, electrochemical properties and kinetic characteristics of the alloys were investigated systematically. the results showed that all the alloys mainly consisted of the (la, mg)ni-3, lani5 phases, and the lattice parameters and the cell volumes of the (la, mg)ni-3 and lani5 phases decreased with increasing ti content. the alloy electrodes could be activated to reach their maximum discharge capacity within five cycles. the cycle life after 100 charge/discharge cycles (c-100/c-max) and the high-rate dischargeability at a discharge current density of 1200 ma/g first increased and then decreased. all the results showed that low-ti content in ab(3)-type hydrogen storage alloys was beneficial to improvements of the overall electrochemical properties, and the optimum overall electrochemical performance of the alloy electrodes was obtained when x = 0.05.
