· JVASP-35597· LiNbSe2

LiNbSe₂ is a ternary metal compound combining lithium, niobium, and selenium, belonging to the class of layered transition metal dichalcogenides. This material is primarily of research interest rather than established in mainstream industrial production, with potential applications in energy storage, photocatalysis, and electronic devices where its layered crystal structure and mixed-metal composition offer unique electronic properties. Engineers would consider LiNbSe₂ for emerging technologies in battery electrodes, catalytic systems, or optoelectronic devices where the combination of lithium's high charge capacity and niobium-selenium's semiconducting characteristics may provide advantages over conventional materials.
