Abstract

The invention discloses a method for preparing a nitrogen-doped carbon gel@(PANI / GO)n supercapacitor for a wireless Bluetooth earphone. The method comprises the steps of preparing a nitrogen-doped carbon gel electrode material by using resorcinol and formaldehyde as a precursor, by using melamine as a nitrogen source, and by using sodium carbonate as a catalyst; dropping PANI onto the nitrogen-doped carbon gel material and repeating n times; pressing the nitrogen-doped carbon gel material into a gel film to obtain an electrode material; cutting the electrode material into cubes, pressurizing asolid electrolyte to obtain a rectangular parallelepiped, then cutting out two slots of the same size as the electrode material from the rectangular parallelepiped, placing the cubic electrode material in the slots, and pressing a flexible nickel slice against the electrode material to obtain a capacitor. The method improves the specific capacitance of the material, achieves a large power density, a wide working voltage window, and fast charging and discharging, and is suitable for an electronic device, such as a Bluetooth earphone, which requires a small and lightweight power supply.
