This invention relates to the field of secondary batteries, specifically, to providing an organic electrolyte for sodium-ion batteries, a preparation method thereof, and its application in sodium-ion batteries. The electrolyte for sodium-ion batteries comprises sodium salts, organic solvents, and additives, wherein the additives include nitrile compounds, sulfonates, and organic sodium salts; this electrolyte can generate a dense SEI layer rich in various inorganic elements, ensuring the sodium... + The rapid diffusion of ions, combined with a suitable reduction in the organic content of the SEI, improves the stability of the SEI during long-term cycling. Compared to sodium-ion batteries assembled using phosphate materials as the positive electrode active material, the capacity retention rate is greater than 80% after 1000 cycles at 1C rate.

This invention provides a vacuum drying device for water-soluble inorganic salt carriers, relating to the field of water-soluble inorganic salt carrier drying technology. It includes a drying chamber and a drying drum. A vacuum pump is located at the back of the drying chamber, and a connecting pipe is fixedly installed on the top of the vacuum pump, with the output end of the connecting pipe connected to the interior of the drying chamber. A mounting frame is fixedly installed on the top of the drying drum. In this invention, the air inside the drying chamber is extracted by the vacuum pump and connecting pipe. Then, a controller activates two heating tube assemblies, which, with the assistance of temperature sensors, heat the interior to the required temperature. Next, the controller activates a drive motor, which drives a drive rod and multiple stirring blades to stir the material, ensuring uniform heating and moisture diffusion within the drying drum, thus ensuring thorough drying and improving the vacuum drying effect on water-soluble inorganic salt carriers.
