Effective in situ coating with iron-based fluoride, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can effectively reduce the formation of membrane on the surface, reduce the loss and polarization of sodium ions in the crystal, and improve the cycle stability of the composite material. The conductivity is very poor. The conductive network constructed with in situ carbon can realize the rapid transportation of electrons and improve the conductivity of the composite cathode material.
The sodium ion cathode material is obtained from the hydrothermal reaction of sodium sodium and iron source. Further, the source of sodium iron is at least one of ferric chloride and ferrous chloride; when ferric chloride is used, ferrous chloride is fecl2 4h2o. Yellow blood salt sodium conducted hydrothermal reaction with iron source, and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC prepared the reaction conditions and parameters of sodium ion cathode material.
Dissolve iron salt in excess fluoroion liquid; preferably the dosage ratio of iron salt to fluoride ionic liquid is 1g: (5~50) ml; fluoroion liquid is at least one of tetrafluoroorate ionic liquid and hexafluorophosphate ionic liquid; further PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preferably, fluoroion liquid is tetrafluoroborate ionic liquid;
