Na2FeP2O7 sodium iron pyrophosphate with a triclinic symmetry (the space group P-1) has been prepared by mechanochemically assisted solid state synthesis. Electrochemical performance of the pristine Na2FeP2O7, NaFeP2O7 prepared by chemical oxidation with NO2BF4 and NaLiFeP2O7 obtained by non-oxidative Na+/Li+ ion exchange with LiBr were studied by galvanostatic cycling in a Li cell with Li as an anode and LiPF6 dissolved in EC+DMC as an electrolyte. XRD, EDX, Mössbauer and NMR spectroscopy studies showed that all the samples were active upon cycling in Li cells which resulted in exchange of one ~Na+ for one Li+ per f.u. to produce a new mixed phase NaLiFeP2O7 with the same triclinic structure as Na2FeP2O7 and good electrochemical performance.
