· La1 Ni5

La1Ni5 is an intermetallic compound in the lanthanum-nickel system, belonging to a class of rare-earth metal hydrides and energy storage materials. This material is primarily investigated for hydrogen storage applications and as a cathode material in nickel-metal hydride (NiMH) batteries, where it demonstrates reversible hydrogen absorption and desorption characteristics that make it valuable for portable power systems and hybrid vehicle batteries. Its selection over competing hydride materials is driven by its favorable hydrogen storage capacity and cycle stability, though it remains more prominent in research and specialized industrial applications than commodity use.
