| titleOfInvention | A kind of manganese dioxide/carbon film composite material with core-shell structure and its preparation method and application |
| abstract | The invention discloses a manganese dioxide/carbon film composite material with a core-shell structure. The polyacrylonitrile film is prepared by electrospinning, and the polyacrylonitrile carbon film is prepared by high-temperature carbonization, which is obtained by quenching in a potassium permanganate solution. Rapidly grown MnO2 nanosheets to obtain a core-shell structure; the core-shell structure consists of carbon fibers as the core, and the MnO2 nanosheet array as the shell. The preparation method comprises the following steps: 1) preparation of polyacrylonitrile film; 2) preparation of polyacrylonitrile carbon film; 3) preparation of birnessite/carbon film composite material with high potassium content. As an electrode material for supercapacitors, it was charged and discharged in the range of 0–1.3 V, and the specific capacity reached 700‑800 mF cm –2 at a current density of 4 mA cm –2 . The present invention uses KMnO4 as the precursor solution, through quenching treatment, not only can in-situ capture potassium ions in the KMnO4 solution, save the pre - intercalation process of potassium ions, greatly improve the specific capacitance of the material; it is conducive to large-scale industrial production and preparation , to realize the development of flexible devices. |
