Z.L. obtained a capacity of 570 mAh g-1, outstanding cycling stability, and more than 90% capacity retention at the charge/discharge rate of C/20.1 Scientists accomplished this feat thanks to the formation of stable SEI and prevention of the dissolution of metal ions by the use of single-crystalline, monodisperse iron (II) fluoride nanorods and ionic liquid (1M LiFSI/Pyr1,3FSI). Am. Further, the anion’s and cation’s co-substitutions (doping of cobalt and oxygen) into nanorod iron fluoride can thermodynamically lower the working potential but improves the reversibility of intercalation reaction.11 Various strategies have been proposed to prevent the dissolution of the metal ions that causes degradation of the cathode and sluggish Li-ion transport.
