Abstract

Intermetallic compounds (IMCs) La2Ni7 and La2Ni6Co were obtained by arc melting technique followed by annealing. Samples were characterized by means of X-ray powder diffraction (XRD). Crystal structure of α-La2Ni7 was refined using single crystal X-ray data. Hydrogen desorption isotherms were obtained for La2Ni7 and La2Ni6Co at T=273K and T=295K. Electrochemical discharge properties of La2Ni7 and La2Ni6Co were investigated. The introduction of Co in alloy led to decreasing of hydride equilibrium pressure.
