A PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preparation method for the cathode material of sodium ion battery, the iron salt is dissolved in the fluorine-containing liquid, and then the mixed solution and the carbon source, sodium ion cathode material are stirred, solvent thermal reaction, to obtain iron-based fluoride and carbon in situ coating modified composite sodium ion battery cathode material.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC The mass ratio of sodium ion cathode material, iron salt and carbon source is 1: (0.01 ~ 0.05): (0.01~0.5); further preferred, the mass ratio of sodium ion cathode material, iron salt and carbon source is 1: (0.01~0.2): (0.1~0.5). Iron salt is trivalent iron salt; further preferred, iron salt is iron nitrate;
Further, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC selects at least one of carbon black, graphite, graphene, carbon nanotubes, carbon fiber, carbon, hard carbon, carbon microspheres; further preferably, the carbon source is super-p, carbon nanotubes, graphene, koqin black, graphite, hard carbon, medium carbon microspheres.
