          Summary

          In the search for high-energy materials, novel 3D-fluorophosphates, Li 2Co 1− x Fe x PO 4F and Li 2Co 1− x Mn x PO 4F, have been synthesized. X-ray diffraction and scanning electron microscopy have been applied to analyze the structural and morphological features of the prepared materials. Both systems, Li 2Co 1− x Fe x PO 4F and Li 2Co 1− x Mn x PO 4F, exhibited narrow ranges of solid solutions: x ≤ 0.3 and x ≤ 0.1, respectively. The Li 2Co 0.9Mn 0.1PO 4F material demonstrated a reversible electrochemical performance with an initial discharge capacity of 75 mA·h·g −1 (current rate of C/5) upon cycling between 2.5 and 5.5 V in 1 M LiBF 4/TMS electrolyte. Galvanostatic measurements along with cyclic voltammetry supported a single-phase de/intercalation mechanism in the Li 2Co 0.9Mn 0.1PO 4F material.
