Abstract

The invention discloses a preparation method and device of a tin / carbon nanotube composite material. A tin wire is vaporized by an electric heating device to obtain tin steam, carbon nanotubes are dispersed in a gas-phase dispersed mist generating device to obtain carbon nanotube dispersion mist, an electric heating blower is started, hot air flow is blown between the tin steam and the carbon nano tube dispersion mist area through a gas flow guide pipeline to obtain low pressure, the tin steam and the carbon nano tube dispersion mist are diffused to the low-pressure area under the action of pressure difference, the tin steam and the carbon nano tube dispersion mist are compounded to obtain a tin / carbon nano tube composite material, and the tin / carbon nano tube composite material is diffused downwards under the next flow of air flow and is collected on an electrostatic adsorption collection plate. The dispersity is ensured, impurities are not introduced, preparation and collection can be realized in a gas phase environment, the equipment is simple, the manufacturing and maintenance cost is low, and safety and reliability are realized.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a preparation method and device of a tin / carbon nanotube composite material. Background technique [0002] The information disclosed in this background section is only intended to increase some understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Lithium metal tin has received extensive attention as an electrode material for lithium-ion batteries due to its high theoretical lithium intercalation capacity. It has not been widely used in actual production. In view of the above problems, studies have shown that it is currently an effective method to suppress particle agglomeration, improve the dispersion of metal tin nanoparticles and material cycle stability by com...
