• stability range of conventional electrolytes. An initial discharge capacity of 132 mA·h·g−1 that is delivered by Li2CoPO4F in a high-voltage electrolyte with fluorinated alkyl carbonates has been reported by S. Amaresh et al., however noticeable capacity fading has been observed upon prolonged cycling [8

• Li2CoPO4F and Li2Co0.9Mn0.1PO4F respectively. A further investigation that includes the optimization of the electrode materials and the development of a high-voltage electrolyte is required to evaluate all potentials of this Li2Co1−xMxPO4F (M = Mn, Fe) fluorophosphate family. Experimental The
