Determination of the Diffusion Coefficient of LiFePO4,ffusion coefficient as a function of the composition unclear. In such a case, the chemical diffusion coefficient as obtained from GITT and IS measurements, may be taken as an effective measure which reflects the intensity of long- and short-range interactions between the intercalated species.

It is well known that natural ferrous phosphate (vivianite) rapidly oxidizes on exposure to air, passing through deepening shades of blue to finally become brown beraunite (3Fe.O.•2P.O.•10H.O). The vivianite obtained by the sol–gel route was dried in air at 100°C. The so-obtained materi

In this chapter we stress this concept reporting on a new reproducible synthetic route to prepare nano-particle LiFePO./C composites, in which the phosphorus, iron and carbon atoms all originate from the same precursor. LiFePO./C composites were prepared from thermal decomposition
