“…However, wide application of Ni-MH battery is hindered due to the high cost of negative electrode materials. Lots of Co-less or Co-free alloys were prepared by substituting Co with foreign metals, such as, Fe, Cu, Si etc., whose raw cost was much cheaper than Co [1]. La 0.73 Ce 0.27 Ni 3.25 Mn 0.35 Al 0.15 Cu 0.75 Fe 0.25 alloy was developed and commercially produced [2].…”

Microstructuresand electrochemical properties of La0.73Ce0.27Ni3.25+xMn0.35Al0.15Cu0.75Fe0.25 alloys are investigated. XRD results indicate that all alloys are identified with LaNi5 phase with CaCu5 type hexagonal structure, and lattice parameter a, c and cell volume V decrease with increasing x value. Maximum discharge capacity first increases from 286.4 mAh/g (x = 0) to 313.2 mAh/g (x = 0.25), and then decreases to 308.9 mAh/g (x = 0.75). High-rate dischargeability of the alloy electrodes increases when x increases from 0 to 0.75. HRD1200 increases with the increase in the I0 and D, and shows a linear relationship with the I0 and D.
