The invention relates to a high specific surface area NiMnO 3 electrode material, a preparation method and application thereof, and belongs to the field of electrode materials. A method for preparing a high specific surface area NiMnO 3 electrode material, wherein potassium permanganate, nickel nitrate, urea and ammonium fluoride are dissolved in water to form a mixed solution; the mixed solution is placed in a microwave hydrothermal reaction kettle, 120 ° C to 200 The powder was obtained by reacting at ° C for 2 h to 5 h; the powder was heat-treated under air conditions, which was obtained. The NiMnO 3 electrode material prepared by the method of the invention is a flower-shaped nanosheet, has a high specific surface area, contains more crystal defects, increases the effective active site of the material, and provides more bits for the material to undergo redox. Point, in essence, improves its capacitance characteristics. |
