ABSTRACT

With the gradual depletion of non-renewable energy sources such as fossil fuels such as coal, oil, and natural gas, as well as the intensification of environmental problems such as water during industrialization, the search for new energy sources is currently a research hotspot. However, due to the poor conductivity of traditional metal oxides and their significant volume expansion during charging and discharging, their application in energy storage is greatly limited. The main focus of this article was on the design, fabrication, and application of chemical nanomaterials in energy storage and conversion. Based on the physical plating and chemical dealloying process, S/NPCu materials with high quality and stability were prepared. The morphology and composition of the samples were analyzed using SEM (Scanning Electron Microscope), TEM (Transmission Electron Microscope), XRD (X-ray Diffraction), etc. Using filtered CuKα, X-ray diffraction was measured on an X-ray diffractometer. In the electrode system, measurements were made using a rotary disc electrode using linear sweep voltammetry and cyclic voltammetry. Even when the charging and discharging rate reached 4Ag-1, MnO2 could still reach 1300mAhg-1, indicating that it still had good stability during the charging and discharging process. Therefore, by designing the electrode structure reasonably, it is possible to achieve rapid and stable energy storage of nanomaterials with extremely low conductivity.
