A sodium ion battery including iron-based fluoride and carbon in situ coating of a modified composite sodium ion battery cathode material.
The complexation agent sodium citrate was dissolved in deionized water at room temperature and reacted. After washing and drying, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC was synthesized to obtain the sodium ion cathode material. For the fluoride liquid was 1-butyl-3-methylimidazole tetrluoroborate or 1-ethyl-3-methylimidazole tefluoroborate, the reaction temperature of the solvent heat was 50℃ to 120℃ and the reaction time was 5 h to 12 h.
After solvent thermal reaction, cooling, wash, drying, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron-based fluoride and carbon situ coating of the modified composite sodium ion battery cathode material; cooling for natural cooling and washing with absolute ethanol and acetone. Take 0.5gfe (no3) 9h2o and dissolve in 15ml ionic liquid, then add a mixed powder of 0.5gsuper-p and 2gna1.7fefe (cn) 6 to the mixed yellow solution,
Stir for 2min, put in 100℃ for solvent heat for 12h. After natural cooling, wash with absolute ethanol and acetone, dry and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC of na1.7fefe (cn) 6 sodium ion cell coated with fef3 0.5h2o and super-p.
