The LiFe(PO4)0.98F0.06/C materials showed better electrochemical performances than LiFePO4/C.
In order to overcome these defaults, one way is to coat the LiFePO4 with electronically conductive materials like carbon, the other way is to prepare ion-doped LiFePO4 materials.
Both methods greatly improve kinetics of materials in terms of capacity delivery, cycle life and rate capability.
The starting materials were weighed in stoichiometric amounts and 20wt% glucose was added to it and homogenized using a mixer.
