· JVASP-42811· Li4CoO2F2

Li4CoO2F2 is an experimental lithium cobalt oxide fluoride ceramic compound under investigation for advanced energy storage applications. This material belongs to the family of lithium-based oxide-fluoride ceramics, which are being researched as potential cathode or solid electrolyte materials for next-generation lithium-ion and solid-state batteries due to their mixed-anion chemistry offering tunable electrochemical and ionic properties. Engineers and materials researchers are exploring such compounds to achieve higher energy density, improved thermal stability, and enhanced lithium-ion transport compared to conventional layered oxide cathodes.
