Fluorinated Graphite as a Fluorine Source for Mechanochemical Synthesis of Lithium Metal Oxyfluorides

F solid-state NMR. Electrochemical measurements indicate improved fluorine incorporation relative to LiF-derived analogues, featured by more symmetric charge-discharge behavior and elevated redox potential. These results demonstrate that fluorinated graphite can serve as an effective fluorine source for mechanochemical oxyfluoride synthesis and provide insight into how heterogeneous C─F bonding environments influence fluorine transfer in the solid state.
