Abstract

The invention discloses a preparation method of an antimony sulfide / graphene composite micro-nano material. The preparation method comprises the following steps: weighing raw materials including graphene oxide dispersion liquid, antimony potassium tartrate, thioacetamide and absolute ethyl alcohol in proportion; mixing the graphene oxide dispersion liquid, antimony potassium tartrate and thioacetamide until the materials are dissolved; dropwise adding absolute ethyl alcohol into the solution, and stirring to obtain a mixed solution; pouring the mixed solution into a reaction kettle, and continuously heating and reacting at 120 DEG C for 12 hours or 18 hours; after the reaction is finished, cooling to normal temperature, taking out the material, and alternately cleaning with high-purity water and absolute ethyl alcohol for at least six times; and centrifugally separating the cleaned material, and drying at 60 DEG C for 12 hours to prepare the antimony sulfide / graphene composite micro-nano material. Graphene in the material shows a flexible thin-surface yarn-shaped appearance with good transparency and wrinkles, it is shown that graphene is well reduced, Sb2S3 nanoparticles are wrapped in a yarn layer of graphene, and it is shown that antimony sulfide and graphene have the excellent recombination rate, so that the electrochemical performance of the material is stable.

Description

technical field [0001] The invention relates to the technical field of electrochemical energy storage materials, in particular to an antimony sulfide / graphene composite micro-nano material prepared by a hydrothermal method and a preparation method thereof. Background technique [0002] The application of various clean energy sources is widely respected. However, it is very difficult to store most clean energy, so the research on energy storage methods is more urgent. Currently, there are roughly four types of energy storage technologies that have become large-scale, namely direct storage of electrical energy, mechanical energy storage, chemical energy storage, and electrochemical energy storage. Among them, compared with the other three energy storage technologies, the electrochemical energy storage phase has a series of advantages such as fast response time and easy maintenance, so it has become one of the development directions of large-scale energy storage technology tod...
