| titleOfInvention | Preparation method and application of composite sodium-ion battery negative electrode material |
| abstract | The invention relates to a preparation method and application of a composite sodium-ion battery cathode material. Weighing 1-2 parts by mass of chlorella and 1 part by mass of tin salt according to the mass ratio of the raw materials, adding the chlorella and the tin salt into deionized water, carrying out magnetic stirring, centrifuging, washing precipitates, and drying in an oven to obtain a light green solid sample; grinding the solid sample into powder, mixing with 4-12 parts by mass of selenium powder, and putting into a corundum boat for calcining to obtain a tin selenide-stannous selenide-chlorella derived carbon compound; and mixing and grinding the tin selenide-stannous selenide-chlorella compound, a conductive agent super P carbon and a binding agent CMC, and coating the mixture on a copper foil to assemble the button cell. Through determination, after 600 times of charge-discharge circulation when the voltage is 0.01-3.0V and the large current density is 1A/g, the specific capacity is stabilized to be more than 300mAh/g, and the capacity retention rate is as high as 85.7%. The raw materials have wide sources and low cost, can be produced in large scale and meet the environmental requirements. |
