Abstract :
A variety of metal elements were partially substituted at 3.3 at% for Ni in LaNi5. X-ray diffraction was performed to find the lattice parameters of each material and to determine the average grain size and lattice strain induced by hydrogen activation. Negative electrodes were made of each material and were cycled in alkaline rechargeable cells to determine the effect of the metal atom substituent on the battery cyclic lifetime
