· JVASP-116261· Li2H

Lithium hydride (Li2H) is an ionic ceramic compound belonging to the metal hydride family, where lithium metal bonds with hydrogen to form a crystalline solid. This material is primarily of research and specialized industrial interest rather than a conventional engineering material, with applications concentrated in nuclear shielding, hydrogen storage research, and high-energy-density battery chemistry exploration. Li2H is notable for its extremely low density and high hydrogen content by weight, making it attractive for neutron moderation and radiation protection in nuclear facilities, as well as for theoretical studies in alternative energy storage systems, though practical deployment remains limited compared to more mature ceramic or polymeric alternatives.

Regulatory Screening

Environmental

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.
