Effect of Heteroatom Doping on Electrochemical Properties of Olivine LiFePO4 Cathodes for High-Performance Lithium-Ion Batteries

“…However, their lower Li + diffusion coefficient (~10 −16 –10 −14 cm 2 s −1 ) and lower electrical conductivity (<10 −9 S cm −1 ) [ 9 , 10 ] limit the further development of LFP cathodes. Therefore, diversified strategies have been undertaken to enhance the electrochemical performance of LFP cathodes, mainly including grain size tuning [ 11 ], carbon coating [ 12 ], and heteroatom doping [ 11 , 13 ]. For example, reducing the size of LFP particles aids in shortening the Li + diffusion distance, thereby enhancing the rate performance and cycling stability.…”

Facilely synthesized LiFePO4nanocomposites with excellent electrochemical properties as cathodes for lithium ion batteries

“…It has been extensively reported that nitrogen-doped carbon improves the active material's electronic and ionic conductivity. 16 As a carbon source, expired beer was used to prepare the LFP cathode material, which provided a discharge capacity of 134 mA h g −1 at a multiplicity of 5C. 17 Zhu et al 18 developed a batch of LiFePO 4 composites with egg lecithin coating.…”
