Is iron fluoride a high energy density cathode for lithium ion batteries?

Provided by the Springer Nature SharedIt content-sharing initiative Iron fluoride, an intercalation-conversion cathode for lithium ion batteries, promises a high theoretical energy density of 1922 Wh kg–1.

Is iron fluoride a good intercalation-conversion cathode for lithium ion batteries?

Iron fluoride, an intercalation-conversion cathode for lithium ion batteries, promises a high theoretical energy density of 1922 Wh kg –1. However, poor electrochemical reversibility due to repeated breaking/reformation of metal fluoride bonds poses a grand challenge for its practical application.

Why is iron based fluoride a good material?

Furthermore, iron-based fluorides are especially popular as fluoride materials. When compared with other materials, iron-based fluoride shows an excellent chemical tailorability due to their distinct functional groups.

Which iron fluoride conversion reaction cathode has the highest energy density?

However, Fe 0.9 Co 0.1 OF shows the highest rate capability across the entire rate range: at 640 mA g −1, the energy density of Fe 0.9 Co 0.1 OF is twice that of FeOF, or six times higher than that of FeF 3, yielding the highest energy density ever reported for iron fluoride conversion reaction cathode materials at similar rates.

Why is iron fluoride a good cathode material?

Among them, iron fluoride is one of the most excellent cathode materials. Due to its outstanding theoretical capacity as well as good thermal stability, it has attracted widespread interest. Meanwhile, the rate performance of SCs has been greatly improved because of the coupling of nanoparticle materials with conductive carbon.

Does metal fluoride improve the electrochemical performance of LIBS?

It is found that metal fluoride can improve the electrochemical performance of LIBs to some extent, but the metal fluoride of nanomaterials shows better performance. This is due to the fact that nanostructures can effectively alleviate various strains resulting from volume changes and increased specific capacity.
