The prepared sodium ion cathode material was placed on an x-ray diffraction instrument and scanned the whole diffraction region with an angle of 2 θ; the sodium ion cathode material prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC was observed and processed. The preparation method of the new sodium ion cathode material, the specific steps are as follows: the pretreatment of feso4 7h2o in a mixture of gas composed of n2, ar and h2 below 500℃ to remove the crystalline water, that is, the feso4 h2o iron source;
Weigh 0.1g of naaf and 3.4g of feso4 h2o iron source in a container, namely the mixed salt, add n, n-dimethylformamide to the mixed salt solution; the prepared mixed salt solution is ground in a wet ball mill of 500 r/min for 20h, the mixture; the prepared mixture is placed in a sealed PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, and add n, n-dimethylformamide to 50ml mixture to the reaction kettle;
The reaction kettle containing the mixture is placed in an oven of 220℃ for 50h, so that the semi-finished product of sodium ion cathode material prepared by the semi-finished product of sodium ion cathode material is centrifuged and dried \ PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, and the sodium ion cathode material is obtained.
