Investigation of the phases formed during the conversion reaction of the C-based FeF2 nanocomposite cathode for Lithium Ion Batteries by PDF

DOI

FeF2 is a conversion reaction material that undergoes a reaction with lithium: FeF2+2Li++2e-2LiF+Fe, which results in a high theoretical capacity, 571 mA/g. Nano-scaling of the iron fluoride particles and mixing them with conductive matrices as carbon has proven a good cycling reversibility of the material when electrochemically reacted with lithium. Consequently, FeF2 emerge among the most promising candidates for high-capacity cathodes for Li-ion batteries. Little is known about phase distribution and characteristics of converted (LiF+Fe) and reconverted FeF2 phases. X-rays are barely sensitive to the LiF phase and to possible Li intercalated in the FeF2 structure thus we suggest here the utilization of neutron scattering experiments to investigate the phases formed during electrochemical de/lithiation. The results will be combined with our previous X-ray,TEM, and magnetization data
