The raw material is dissolved in deionized water with fecl2 4h2o and the complexed agent sodium citrate at room temperature and reacted. After washing and drying, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC obtained the na1.7fefe (cn) 6 sodium ion cathode material. Dissolve 0.5gfe (no3) 9h2o in 20ml ionic liquid, then add 0.3g of graphene and 2gna0.7fefe (cn) 6 to the mixed yellow solution, stir for 3min,
The solvent was heated at 100℃ for 12h. After natural cooling, it was washed with absolute ethanol and acetone, dried and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC the na0.7fefe (cn) 6 sodium ion battery coated with fef3 0.5h2o and graphene in situ. Na 4 fe (cn) 6 10h2o was dissolved with fecl2 4h2o and complexed sodium citrate at room temperature and reacted, after washing and drying, the sodium ion cathode material of na1.7fefe (cn) 6 was synthesized.
Dissolve 0.5gfe (no3) 9h2o in 15ml ionic liquid, then add 2gna1.7fefe (cn) 6 powder to the mixed yellow solution, stir for 3min, heat solvent at 100℃ for 12h. After natural cooling, wash with absolute ethanol and acetone, dry the na1.7fefe (cn) 6 sodium ion cell coated with fef3 0.5h2o in situ.
