In this distorted octahedral structure, there is a presence of a one-dimensional diffusion path (parallel to the b-axis) for the lithium-ion movement . The P-O covalent bond leads to the high polarisation of the oxygen atoms due to the inductive effect of phosphorous. This in turn weakens the covalence of the Fe-O bond leading to a higher circuit voltage (VOC) . The LFP is characterised by a flat charging and discharging curve due to the structural similarity of the two boundary phases. This leads to high cycling stability. The major problem associated with LFP chemistry is that it has poor electrical and lithium-ion conductivity. The problem of oxygen evolution is solved in LFP due to strong covalent bonds with the phosphate molecule . LFP also shows excellent thermal capacity . It is characterized by a stable structure with it being inexpensive and ecologically acceptable, even though it has the lowest electronic and ionic conductivity of any commercial LiB cathode material.
