Abstract

In order to improve the cycling stability of AB₅ type alloy electrodes, rapid quenching technology and new alloy composition design were employed. A hydrogen storage alloy with nominal composition La _0.6Ce_0.4Ni_3.6Co_0.65Mn _0.4Al_0.2Ti_0.05(FeB)_0.1 was prepared by vacuum magnetic levitation melting under high purity argon atmosphere, followed by rapid quenching at different cooling rates. XRD results show that all alloys exhibit the single-phase CaCu₅-type structure. Electrochemical tests indicate that rapid quenching can slightly improve the cycling life of the alloy. Nevertheless, the high-rate dischargeability of the quenched alloys is lower than that of the as-cast alloy.
