Li2 Co4 O8
semiconductor· Li2 Co4 O8
Li₂Co₄O₈ is a lithium cobalt mixed-valence oxide semiconductor belonging to the spinel or layered oxide family, composed of lithium, cobalt, and oxygen in a 1:2:4 stoichiometric ratio. This compound is primarily of research interest for energy storage and electrochemical applications, particularly in lithium-ion battery cathode materials and electrochemical sensors, where its mixed cobalt oxidation states enable electron transfer and ion transport. While not yet in widespread commercial production, oxides in this compositional family are notable for their potential to improve cycle life, thermal stability, and rate capability compared to single-phase cobalt oxide alternatives.
