Problems solved by technology

[0004] Existing pure graphene has insufficient active sites and is not selective
It does not have a good matching degree in practical applications; and the catalytic activity of graphene-based materials in the oxidation-reduction reaction (ORR) in acidic media is low, which is not enough to replace noble metals as electrocatalysts. In order to make up for the defects of graphene, in addition to In addition to controlling the morphology of graphene, doping graphene is another effective method

Abstract

The invention discloses a method for manufacturing a nitrogen-doped nano-carbon intercalated graphene cell. The method comprises the following steps of: intercalating nano-scale nitrogen-doped nano-carbon and graphite in a closed dust-free space through intercalating equipment. The method has the advantages that graphene is a true surface-type material; the specific surface area of the ideal single-layer graphene is up to 2630 m<2> / g; the specific surface area of the graphene containing defects and impurities is larger; and therefore, the graphene becomes an important choice for next-generation energy storage and electrode materials.

Description

Technical field [0001] The invention relates to a manufacturing method of graphene batteries, in particular to a manufacturing method of nitrogen-doped nano-carbon intercalation graphene batteries. Background technique [0002] Graphene is a new nanomaterial composed of sp2 hybridized carbon atoms densely packed into a single-layer two-dimensional honeycomb lattice structure. High-quality nitrogen-doped carbon nanographene powder GN-100 is usually composed of 1-5 atomic layer graphene nanosheets. The lateral size of these nanosheets is 0.5-5 microns, and the average surface area is 500-700m2 / g. The nitrogen doping content is 1.0-3.0at%, and the electrical conductivity exceeds 1000S / m. The nitrogen content in the nitrogen-doped carbon nanographene can be controlled within the range of 0.6at.% to 5at.% by adjusting the doping process. [0003] Graphene has high electronic properties, high specific surface area, and excellent mechanical flexibility, and can become a potential negati...
