Embodiment Construction

[0020] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0021] refer to figure 1 , the manufacture method of a kind of cathode graphene of the present invention comprises following manufacture process:

[0022] S1. Penetrant dispersion: 2D graphene materials with less than four layers are added to the penetrant for dispersion. The penetrant is a non-ionic chelating agent (NH4)4‧EDTA or (NH4)4‧PTDA, and the penetrant is mixed with graphene The molar ratio is 2:1;

[0023] S2. Boron ion dispersion: add boron oxide to the mixture for further dispersion, so that boron oxide is evenly dispersed on graphene, so that the graphene lattice is fully exposed to boron ions. The mixing molar ratio of boron oxide and graphene is 1:1 ;

[0024] S3. Boron ion intercalation reaction: Put the mixed material fully contacted with boron ions into the reactor for ion infiltration reactio...

Abstract

The invention discloses a manufacturing method of negative electrode graphene. The manufacturing method comprises the following steps of adding the graphene into a penetrating agent for dispersion, wherein the penetrating agent is a non-ion chelate; adding boron oxide into the mixture for further dispersion so that the boron oxide is uniformly dispersed on the graphene and graphene lattices are in full contact with boron ions; placing the mixed material in full contact with the boron ions in a reaction kettle for ion permeation reaction; and performing cleaning after the fabrication of the negative electrode graphene is completed through reaction. According to the manufacturing method of the negative electrode graphene, the boron ions are mainly embedded onto the graphene lattices to be used as a negative electrode of a battery, and the boron material is low in cost, is easy to obtain, has positive piezoelectric potential characteristic and is an excellent material of the graphene battery negative electrode. By the fabrication method, the function development of the graphene is achieved, and the application range of the graphene is expanded.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a method for manufacturing cathode graphene. Background technique [0002] The application of graphene has attracted the attention of the whole world, but the research on graphene is still in its infancy. Graphene is a very unique two-dimensional new material. However, the application of this new material is mainly in the addition of materials. The development of deeper and functional materials is the direction of scientific and technological progress. This requires that raw materials must be materials with functional properties. The material made from the original graphene is called N-type graphene, which means that the current graphene material as an additive material is called N-type graphene without its own characteristics and without ions. The meaning of means: no ionic graphene or neutral graphene without ionic properties. It is necessary for us to do work on the produc...
