· JVASP-48055· Li4CoO4

Li₄CoO₄ is a lithium-cobalt oxide ceramic compound belonging to the family of lithium metal oxides, typically studied as a cathode material and solid electrolyte component in advanced battery and energy storage research. This material is primarily investigated in academic and industrial R&D contexts for lithium-ion and solid-state battery applications, where its ionic conductivity and electrochemical stability are of interest; it represents part of the broader effort to develop high-energy-density battery systems and solid electrolyte materials that could eventually replace conventional liquid electrolyte technologies in next-generation energy storage devices.
