Abstract
In addition of the poor intrinsic conductivity of LiFePO4 particle, surface effects become increasingly important, and can eventually dominate the physical and the chemical properties when the size decreases below 100 nm. Carbon coating appeared to overcome the drawback of highly resistive LiFePO4 powders and to cure the disordered surface layer that reduces the electrochemical performance of non-coated sample. Here, we analyze the effect of the carbon coating on the LiFePO4 particles that meets a worldwide success as a positive electrode for commercial Li-ion batteries.
