· JVASP-46919· Li7CoOF7

Li7CoOF7 is an oxyfluoride ceramic compound combining lithium, cobalt, oxygen, and fluorine—a composition category of interest for solid-state electrochemistry and energy storage research. This material belongs to the family of lithium-containing ceramics being explored for solid electrolytes and cathode materials in advanced battery systems, where the mixed anion framework (oxide + fluoride) can provide improved ionic conductivity and electrochemical stability compared to conventional oxide ceramics alone.
