Graphene/mno electrode, preparation method therefor, and high energy density supercapacitor |
| abstract |
The present invention provides a method for preparing a graphene/MnO electrode, comprising the following steps: A) forming a mixed liquid containing MnO2 nanoneedles and graphene oxide, the mass ratio of the MnO2 nanoneedles to the graphene oxide being 1:(0.5-12); B) forming a film from the mixed solution; and C) performing flash reduction on the film, and obtaining a graphene/MnO electrode. The present invention provides, by reasonably designing reaction conditions, a low-cost and one-step flash reduction process for preparing a high-performance graphene/MnOx electrode. According to the simple method, a high-quality porous graphene lattice can be fabricated; in addition, a pseudocapacitive active MnOx nanomaterial can simultaneously be effectively synthesized and embedded. Ultra-high capacitance (up to 1706 F·g-1) beyond the theoretical limits of pure graphene and MnOx is demonstrated when using the fabricated electrode. The present invention also provides a graphene/MnO electrode and a high energy density supercapacitor. |
