“…The very low capacity of sample P-b is attributed to its amorphous nature as shown above from XRD data. The low capacity of amorphous material is in agreement with the work of Wilhelm et al [51]; however, most of the amorphous materials showed high capacity when compared to crystalline one [52][53][54][55]. It is worth mentioning that Patoux et al [56] synthesized TiP 2 O 7 ; however, their work was not focusing on the mesoporous structure.…”

“…The reversible redox processes are comparable in potential to previously reported FePO 4 $2H 2 O from Wang et al, 28 or highly defective Li x Fe y PO 4 samples from Hamelet et al 12 In addition, structural disorder might be responsible for a broadening of incremental capacity peaks characterizing the lithium (de)insertion reactions, as a slight change of bond lengths and angles around the transition metal ion can affect its redox potential through the inductive effect. Therefore, the gradual peak sharpening from sample B to D, together with an increase of the corresponding integrated capacity along aging, suggests tavorite crystallization in agreement with the conclusions drawn from M€ ossbauer spectroscopy (see Fig.…”

“…In the electrochemical field, it is imperative that FePO 4 contains no undesirable impurities. Wang et al [49] proposed that the residual moisture in FePO 4 can react with Li + to produce LiOH (Fig. 6a, b), resulting in a higher first capacity and an irreversible degradation in the subsequent cycles.…”
