Embodiment Construction

[0026] Weigh 10g tin tetrachloride pentahydrate (SnCl 4 5H 2 O, CAS: 10026-06-9) was dissolved in 1 liter of absolute ethanol. Ammonia water is slowly dropped into the alcohol solution to increase the pH of the alcohol / water mixture, and it can be observed that flocculent colloids are formed in the solution. Stir the solution continuously to complete the hydrolysis of tetravalent tin. After three hours, the final pH is controlled at about 8. Stand the solution, it can be seen that the solution is layered, the upper layer is a clear alcohol aqueous solution, and the lower layer is a white Sn hydrolyzate (colloidal). Chloride ion exchange resin is added to the layered mixture to carry out exchange and removal of chloride ions. Separation of saturated chloride ion exchange resin particles, adding fresh chloride ion exchange resin, repeated several times until the concentration of chloride ion in the alcohol aqueous solution is lower than 5mg / L. Distill the alcoholic aqueous s...

Abstract

The invention provides a method for preparing a carbon-tin composite conducting film. The method comprises the following steps: putting tin chloride in an alcohol-water solution with the pH value of greater than 7 and smaller than 9, carrying out hydrolysis and alcoholysis, removing chlorine ions, drying and dehydrating to obtain the solid which is used as a carbon-tin precursor, wherein the mass ratio of the alcohol to the water in the alcohol-water solution is greater than 9:1; and putting an inert substrate on one end of a pipe furnace, putting the solid obtained by tin chloride hydrolysis and alcoholysis at the center of the pipe furnace, introducing an inert atmosphere, and treating for more than 3 hours while controlling the central temperature of the pipe furnace at 600-800 DEG C and the temperature of the inert substrate end to be 50-100 DEG C lower than the center of the pipe furnace. The method can be used for forming the carbon-tin composite conducting film on the surface of a conducting substrate material, nonconducting substrate material or the like. The prepared C-Sn film can be used as an electrode material.

Description

technical field [0001] The invention relates to a preparation method of a carbon-tin composite conductive film, which belongs to the field of new materials. Background technique [0002] Carbon is an electrically conductive material with a wide range of applications in energy, environment, defense and many other fields. The composite materials of carbon materials and metals also exhibit many excellent properties. The simplest example is carbon steel materials. Due to the addition of about 2% carbon, the strength and hardness of steel are greatly increased. In recent years, composite materials of carbon and metal nanoparticles have excellent performance in the fields of energy and catalysis, and have become a hot research topic. The composite material of carbon and tin metal is a new type of material developed in recent years. Researchers have found that the composite material can be used as the positive electrode material of lithium batteries, replacing traditional graphite...
