This invention relates to the field of sodium-ion battery technology, and discloses a sodium-ion cathode material, its preparation method and application, a sodium-ion battery, a sodium-ion battery pack, and a device. The sodium-ion cathode material includes a matrix and a coating layer covering the matrix; the matrix has the composition shown in Formula I: Na 1‑x [Ni y Mn z M u Ti v O2 Formula I; the coating layer has the composition shown in Formula II: Na 2‑β Ti 6‑α M′ α O 13 Formula II. This sodium-ion cathode material possesses characteristics such as high ionic and electronic conductivity, strong structural stability, and strong chemical stability. Furthermore, using this composite cathode material in sodium-ion batteries can effectively improve the battery's electrochemical performance.

The application relates to a preparation method of a lithium battery diaphragm and belongs to the technical field of lithium battery preparation. The method is as follows: epoxy resin, a diluent, a curing agent 1 and an oleophilic emulsifier are uniformly mixed to obtain dispersion liquid 1; an electrolyte solution is constantly dropped into the dispersion liquid 1, constant-temperature high-speed stirring is carried out, and a water-in-oil emulsion is obtained; under constant temperature, deionized water, a hydrophilic emulsifier and a curing agent 2 are uniformly mixed to obtain dispersion liquid 2; the water-in-oil emulsion is added into the dispersion liquid 2, high-speed emulsification is carried out, and a water-in-oil-in-water emulsion system is obtained; the water-in-oil-in-water emulsion system is subjected to temperature rising and curing; after curing, centrifugal separation, washing and drying are carried out, and a solid nanometer adhesive is obtained; the solid nanometer adhesive is ground, then is uniformly coated in a mold and is subjected to high-temperature treatment, and the lithium battery diaphragm is obtained. The electrolyte solution is selected as the inner water phase of the water-in-oil emulsion, the internal osmotic pressure of the emulsion can be increased, fusion between the emulsions can be prevented, and the particle size is increased.
