Description	Two iron titanium phosphates, Fe0.5TiOPO4 and Fe0.5Ti2(PO4)3, were prepared, and their crystal structures and electrochemical performances were compared. By correlating the electrochemical performances with the structural studies, new insights are achieved into the electrochemical behaviour of the Fe0.5TiOPO4 anode material, suggesting a combination of intercalation and conversion reactions. The first discharge of lithium ion cells based on Fe0.5Ti2(PO4)3 materials showed electrochemical activity of Ti4+/Ti3+ and Fe2+/Fe0 couples in the 2.5–1 V region. Below this voltage, the discharge profiles are typical of phosphate systems where Li3PO4 is a product of the electrochemical reaction with lithium; moreover, the electrolyte solvent is reduced.
