We present a review of the structural, physical, and chemical properties of both the bulk and the surface layer of lithium iron phosphate (LiFePO4) as a positive electrode for Li-ion batteries. Depending on the mode of preparation, different impurities can poison this material.
Lithium iron phosphate batteries generally consist of a positive electrode, a negative electrode, a separator, an electrolyte, a casing and other accessories. The positive electrode active material is olivine-type lithium iron phosphate (LiFePO4), which can only be used after modification such as carbon coating and doping.
The structure of lithium iron phosphate (LFP)-based electrodes is highly tortuous. Additionally, the submicron-sized carbon-coated particles in the electrode aggregate, owing to the insufficient electric and ionic conductivity of LFP.
