· JVASP-42605· Li4CoO3F

Li4CoO3F is a lithium-cobalt oxyfluoride ceramic compound under investigation for energy storage applications, particularly as a potential cathode or electrode material in advanced lithium-ion and solid-state battery systems. This material belongs to the family of lithium transition metal oxides/fluorides, which are being explored to improve energy density, thermal stability, and cycle life beyond conventional cathode chemistries. While primarily in the research phase, compounds in this family are notable for their ability to store and release lithium ions efficiently, making them candidates for next-generation battery technologies where conventional layered oxides face limitations in performance or safety.
