Abstract

The invention relates to a method for preparing a micro-nano material. The method comprises the following steps: providing submicron particles; adding a prepolymer monomer solution having a carbon content of 50% or more and an initiator to the submicron particles to obtain polymer-coated submicron particles, wherein one of the prepolymer monomer solution having the carbon content of 50% or more and the initiator is respectively added; and sintering the polymer-coated submicron particles to prepare a micro-nano material of carbon-coated nanoparticles. The invention relates to a micro-nano material prepared by the method, and a battery prepared by the micro-nano material. The micro-nano material prepared by the method has the advantage that a carbon structure with stable properties can be coated on the surface of the nanoparticle so as to solve the problem of the instability of the nanoparticle.

Description

【Technical field】 [0001] The invention relates to the field of preparation of nanometer materials, in particular to a micronanomaterial, a preparation method thereof, and a battery. 【Background technique】 [0002] Nanoparticles are a new type of material that emerged in the late 20th century. The size of the powder is usually between 1nm and 100nm. Due to the macroscopic quantum tunneling effect, quantum size effect, and surface and interface effects, many properties of the substance change, showing different The singular properties of magnetism, light, electricity, sound, heat, force and chemistry of macroscopic objects and individual atoms. However, due to the characteristics of high activity and easy aggregation of nanoparticles, the application of nanoparticles is severely limited, mainly including that nanoparticles are prone to flammability and explosion during storage and transportation; reaction, making it inactive. Therefore, finding nanoparticles that can exist s...
