· JVASP-26279· LiFeAsO4

LiFeAsO4 is an olivine-structured ceramic compound combining lithium, iron, arsenic, and oxygen—a member of the polyanion phosphate/arsenate family of materials under investigation for energy storage applications. This compound is primarily a research material being explored as a potential lithium-ion battery cathode material, offering theoretical advantages in terms of thermal stability and cost compared to conventional layered oxide cathodes, though it remains in the developmental stage with limited commercial deployment. The material is notable within the battery research community for its structural framework that could enable stable lithium intercalation, though practical challenges around electronic conductivity and arsenic toxicity concerns have limited its industrial adoption compared to phosphate-based alternatives like LiFePO₄.
