Embodiment Construction

[0025] figure 1 is a schematic diagram of the distribution of holes in an embodiment of the present invention. Please refer to figure 1 , in one embodiment of the present invention, the network structure of the stanene material contains a plurality of holes, and each of the holes is given by the formula n=6r 2 Defined, wherein n is the number of atoms of the stannene material occupied by the holes, and r is the number of layers of atoms of the stannene material occupied by the holes.

[0026] by figure 1 Take (a) as an example. (a) The four vertices of the parallelogram in the figure are respectively located at the centers of the four holes. Take hole A as an example. Since the atomic structure of the stanene material is a hexagon, the hole A is formed by cutting out (that is, occupying) the six stanene atoms forming the hexagon. In the present invention, a hexagon is set as the first layer. Then, the 6 hexagons adjacent to this hexagon make up the second layer. The 12...

Abstract

The invention relates to the field of materials science, particularly a stanene material, a preparation method thereof and a battery employing the stanene material. The stanene material comprises at least one layer of atomic structure. A plurality of holes are distributed in the atomic structure. The holes are formed by removing atoms. A relationship between the number n of the atoms removed fromeach hole and the occupied layer number r is n=6r<2>.

Description

technical field [0001] The invention belongs to the field of materials science, and in particular relates to a network-structured stannene material. Background technique [0002] Currently, rechargeable metal-ion batteries based on 2D materials have attracted extensive attention due to their high energy storage density, good rate performance, and good cycle stability. Among traditional two-dimensional materials, graphite has low cost, high energy storage and good cycle performance, but its capacity is low and its binding ability is weak. Therefore, finding suitable anode materials has become an important challenge in the synthesis of high-performance metal-ion batteries. Contents of the invention [0003] The invention aims to provide a stannene material to improve the electronic capacity of traditional two-dimensional materials and enhance the binding ability. [0004] The above-mentioned stannene material, the structure of the stannene material contains a plurality of ...
