中文摘要	ab(2-x)%lani5 (x =0, 1, 5, 10) composite alloys were prepared by melting zr0.9ti0.1ni1.1mn0.6v0.3 with a small amount of lani5 alloy as addition. the microstructure and electrochemical characteristics of the composite alloys were investigated by means of xrd, sem, eds and electrochemical measurements. it was shown that lani5 addition does not change the basic hexagonal c14 laves phase of ab(2) alloys, but some second phases have segregated. it was found that the addition of lani5 greatly improves the activation property, high-rate dischargeability (hrd) and charge-discharge cycling stability of ab(2) laves phase alloy. at current density of 1200 ma/g, hrd of the alloy increases from 38.92% (x =0) to 60.09% (x = 10). the capacity retention of the alloy after 200 charge-discharge cycles increases from 57. 10% (x = 0) to 83.86% (x = 5) and 67.31% (x = 10). the improvement of the electrochemical characteristics caused by lani5 addition seems to be related to formation of the second phases.
