· Li4 Co4 O8

Li₄Co₄O₈ is a mixed-valence lithium-cobalt oxide ceramic compound belonging to the family of layered transition-metal oxides with potential lithium-ion storage capability. This material is primarily investigated in battery research and solid-state electrochemistry contexts, where its mixed oxidation states and layered structure make it a candidate for lithium-ion intercalation and electrochemical energy storage applications. While not yet commercialized at scale, this compound family is notable for exploring alternative cathode and anode materials with improved cycling stability, energy density, or cost profiles compared to conventional lithium-cobalt oxide (LCO) and other commercial battery oxides.
