Primary Lithium Batteries are substantial in many applications, particularly in industrial niche sectors. Graphite oxifluorides and their precursors, graphite oxides, are promising materials for the cathodes. We explored two-step synthesis combining Hummers' oxidation and solid-gas fluorination. Temperature of oxidation was key parameter to control OH, COC and COOH ratio. Direct fluorination and controlled fluorination were processed at laboratory and scaled-up. Because of complexity of the materials and specificity at each scale, we cross-checked the data from several techniques for structure (XRD, TGA, Raman spectroscopy...) and chemistry (IR, MAS NMR, XPS...) for an accurate picture. We tested the broad set of materials. Galvanostatic di...
