The new sodium ion cathode material nafeso4f has a first reversible capacity of 140 mah / g and has good cycling performance; Therefore, the new nafeso4f of sodium ion cathode material prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC has wide application prospect. The molar ratio of feso4 7h2o iron source to naf is 1:1~2.
High boiling point organic solvents are ethylene glycol or propylene glycol or n, n-dimethylformamide; the mass ratio of mixed salt to high boiling point organic solvents is between 1:2 and 5:1. Further, the mass ratio of the mixture to the high boiling point organic solvent is between 1:10 and 1:50. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC The preparation of new sodium ion cathode material nafeso4f has a wide range of raw material sources, and the preparation of new sodium ion cathode material nafeso4f process is very simple, easy to achieve industrial production.
Pretreat feso4 7h2o in an inert atmosphere or reducing atmosphere; pretreat in an inert atmosphere or reducing atmosphere is to prevent oxygen from trivalent iron to ensure the purity of raw material. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC The method of preparing the new sodium ion cathode material nafeso4f has the advantages of simple process, low cost, stable cathode material phase and controllable size, therefore, the preparation method is suitable for popularization and application in the field of chemical power supply technology.
