Abstract
Li-Ion and Ni-MH batteries are the best candidate for Electric Vehicles. Despite higher energy densities of Li-Ion batteries, because of economical reason Ni-MH Batteries are still attractive for scientist. In this investigation Cerium rich MmNi3.55Co0.75Mn0.4Al0.3 has been produced via Vacuum Arc Remelting Process. Phase characterization has shown that the predominant crystallographic phase is Hexagonal type with AB5 chemical formulation. Volumetric Sievert test has shown that the alloy could store 1%wt percent hydrogen at room temperature. Electrochemical analysis with Evium-Stat has shown that the energy density which the alloy can reversibly deliver is about 150 mAh/g.
