Embodiment Construction

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

[0021] see figure 1 , a kind of manufacture method of anode graphene of the present invention, comprises following manufacture process:

[0022] S1. Penetrant dispersion: Add the 2D graphene material below four layers into the penetrant for dispersion, the penetrant is a non-ionic chelating agent (NH4) 4‧EDTA or (NH4) 4‧PTDA, the mixture of the penetrant and graphene The molar ratio is 2:1;

[0023] S2. Manganese ion dispersion: Manganese oxide is added to the mixture for further dispersion, so that manganese oxide is uniformly dispersed on the graphene, and the graphene lattice is fully contacted with manganese ions. The mixing molar ratio of manganese oxide and graphene is 1:1 ;

[0024] S3, manganese ion intercalation reaction: put the mixture material fully contacted with manganese ions into the reaction kett...

Abstract

The invention discloses a manufacturing method of positive 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 manganese oxide into the mixture for further dispersion so that the manganese oxide is uniformly dispersed on the graphene and graphene lattices are in full contact with manganese ions; placing the mixed material in full contact with the manganese ions in a reaction kettle for ion permeation reaction; and performing cleaning after the fabrication of the positive electrode graphene is completed through reaction. According to the manufacturing method of the positive electrode graphene, the manganese ions are mainly embedded onto the graphene lattices to be used as a positive electrode of a battery, and the manganese material is low in cost, is easy to obtain, has positive piezoelectric potential characteristic and is an excellent material of the graphene battery positive 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 present invention relates to the technical field of graphene, in particular to a method for manufacturing anode graphene. Background technique [0002] The application of graphene has attracted worldwide attention, but the research on graphene is still in its infancy. Graphene is a very special two-dimensional new material. However, the application of this new material is mainly based on material addition. The development of deeper and functional materials is the direction of scientific and technological progress, which requires raw materials. to produce materials with functional properties. The material produced by the original graphene is called N-type graphene, which means that the current graphene material used as a material for additive purposes does not have independent characteristics and does not have ions itself. The graphene is called N-type graphene, N The meaning refers to: graphene without ionic properties no ionic graphene or neutra...
