LaNi5
metal· LaNi5
LaNi5 is an intermetallic compound composed of lanthanum and nickel, belonging to the rare-earth metal hydride family. It is primarily used as a hydrogen storage material and electrode material in nickel-metal hydride (NiMH) batteries, where its ability to reversibly absorb and release hydrogen makes it valuable for rechargeable energy storage applications. Compared to alternatives, LaNi5 offers favorable hydrogen storage capacity and kinetic properties, making it a well-established choice in portable power and hybrid vehicle battery systems, though it has gradually been supplemented by newer rare-earth hydride variants with improved performance.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
