Description

Technical field

[0001] The present invention involves the field of new energy materials technology, and the preparation of supercapacitors electrode materials involves the preparation of supercapacitors electrode materials. It is a preparation method of graded structure graphene / carbon nanoma hybrid. Background technique

[0002] As a two -dimensional nano -carbon material, graphene has the characteristics of unique chemical structure, large ratio area, high conductivity, excellent mechanical properties, and other characteristics.As well as the field of high -performance composite materials, extensive application prospects are present.However, because graphene is prone to irreversible reunion due to the effect of Van Dehua, it makes it difficult for single -layer graphene to play its inherent excellent characteristics.Therefore, the problem of solving the gatsene layer of graphene is an urgent need to solve.

[0003] Because of its excellent conductivity and chemical stability, o...
