Carbon compound chalcogenide compound material and preparation method and application thereof
The invention provides a carbon-composite chalcogenide composite material and a preparation method and application thereof, and belongs to the technical field of secondary ion batteries. The carbon-composite chalcogenide composite material provided by the invention includes chalcogenide nanocrystals and chaotic layers Graphite carbon, the chalcogenide nanocrystals are located in a networked framework structure of disordered layered graphite carbon, and the material of the chalcogenide nanocrystals includes at least one of metal chalcogenides, silicon sulfide and silicon diselenide The carbon-composite chalcogenide composite material provided by the present invention can still maintain a higher mass specific capacity and a coulombic efficiency of more than 99% when it is cycled for more than 100 times of charging and discharging, and has excellent cycle stability and rate performance.
 
Computational simulation of several low-dimensional nanostructured materials
Nanomaterials have novel electronic structures and special physical and chemical properties, and have potential application prospects in the fields of optics, electricity, magnetism, catalyst carriers, sensors, drug storage and slow release. Silicon carbide is a wide-band gap semiconductor material with The characteristics of high melting point, high hardness, high thermal conductivity and radiation resistance are potential materials for designing electronic devices under extreme conditions; boron nitride has good chemical stability, electrical insulation, high thermal conductivity and high hardness and other excellent properties; Silicon dioxide, germanium dioxide, silicon sulfide and germanium disulfide are typical IV-VI compounds with excellent electronic and optical properties and are widely used in glass, ceramics, optoelectronic devices and information industries. Due to the limitations of experimental methods The current understanding of the structure and properties of low-dimensional nanomaterial systems is relatively lacking, so relevant theoretical research is carried out
