چکیده مقاله
With the reduction of fossil fuel reserves and the increase in the price of petroleum products, the development of electric and hybrid cars has become the focus of attention of car manufacturers. In order to achieve this object, it is inevitable to develop rechargeable batteries with high energy storage capacity and reasonable price. Although lithium batteries have a greater capacity for energy storage, the use of these batteries in electric vehicles is not economical due to their high price, and other batteries such as nickel-metal hydride batteries are proposed as alternatives. Metal hydrides are widely used as hydrogen storage material for use in fuel cells and internal combustion engines, energy converters, and as electrodes in nickel metal hydride batteries . Meanwhile, LaNi5-based alloys with easy activation conditions, high kinetics, almost good cyclability in absorption and desorption, hydrogen storage capacity in the range of 1.4 to 1.6 wt% and also excellent electrochemical properties are one of the suitable options . The purpose of the present research is to synthesize a hydrogen absorbent alloy with the composition of La2Mg0.9Y0.1Ni10Mn0.5, and then investigate the microstructure, hydride and electrochemical properties of this alloy.
