Li2I
ceramic· JVASP-115189· Li2I
Li₂I is an ionic ceramic compound composed of lithium and iodine, belonging to the family of lithium halides. This material is primarily of research interest for solid-state battery applications, where it serves as a potential solid electrolyte or electrolyte component, leveraging lithium's high ionic mobility and iodine's electrochemical stability. Li₂I and related lithium halide ceramics are being investigated as alternatives to conventional liquid electrolytes in next-generation energy storage, offering potential advantages in thermal stability, safety, and energy density—though materials in this class remain largely in development phases outside specialized laboratory and industrial battery research settings.

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.
