Abstract

Description
The present invention relates to an inorganic nanoparticle-carbon nanotube composite, a method for producing the inorganic nanoparticle-carbon nanotube composite, and a lithium secondary battery including the composite.
Recently, carbon nanotubes among the carbon isotopes have attracted attention in the field of electronic information communication, environmental materials and energy because of their excellent strength and conductivity.
Methods for synthesizing carbon nanotubes include electric discharge, laser deposition, hydrothermal synthesis, and chemical vapor deposition. Among them, carbon nanotubes synthesized by chemical vapor deposition can obtain simple and high purity samples, and can synthesize carbon nanotubes in a vertical orientation. This synthesis method has an advantage that the structure control of carbon nanotubes is easy.
Catalysts are needed to synthesize carbon nanotubes by chemical vapor deposition. Carbon nanotubes are usually grown on the surface of metal particles by chemical vapor deposition using metal particles such as Fe, Co, Ni, Pt, Au, and Al as catalysts. However, metal oxides and metal chalcogenides other than metal particles have not been studied as catalysts for growing carbon nanotubes. However, when carbon nanotubes are synthesized by the chemical vapor deposition method, expensive metal particles are used, and a reaction occurs at a high temperature. Therefore, there is a need for a method of replacing the catalyst with a catalyst that is cheaper than the metal particles used as a catalyst, and further research is needed to synthesize carbon nanotubes at a low temperature rather than a high temperature.
