Embodiment 1

[0035] First need to weigh 1mmol CuCl 2 , into a 50mL beaker, then add 40mL deionized water, stir, then add 1mmol Na 2 CO 3 and 1mL of triethylamine solution, stirred for 10 minutes, then ultrasonicated for 5 minutes, and then directly put into the microwave oven, set the power to 300W, and the time was 20 minutes, and washed several times with deionized water and absolute ethanol, and then in Dry in an oven at 60°C for 6 hours to obtain a copper oxide nanoshuttle sample. Such as figure 1 Shown product is identified as copper oxide through X-ray powder diffraction; Carry out morphology analysis to copper oxide with scanning electron microscope (SEM), from figure 2 It can be seen that its morphology is nanoshuttle. Excellent electrochemical cycle performance and specific capacitance can be obtained from image 3 see.

Embodiment 2

[0037] First need to weigh 1mmol CuCl 2 , into a 50mL beaker, then add 40mL deionized water, stir, then add 1mmol Na 2 CO 3 and 1mL of triethylamine solution, stirred for 10 minutes, then ultrasonicated for 5 minutes, and then directly put into the microwave oven, set the power to 200W, and the time was 20 minutes, and washed several times with deionized water and absolute ethanol, and then in Dry in an oven at 60°C for 6 hours to obtain a copper oxide nanoshuttle sample. The morphology of copper oxide was analyzed by transmission electron microscopy (TEM). Figure 4 It can be seen that its morphology is nanoshuttle.

Embodiment 3

[0039] First need to weigh 1mmol CuCl 2 , into a 50mL beaker, then add 40mL deionized water, stir, then add 1mmol Na 2 CO 3 and 1mL of triethylamine solution, stirred for 10 minutes, then ultrasonicated for 5 minutes, and then directly put into the microwave oven, set the power to 400W, and the time was 20 minutes, and washed several times with deionized water and absolute ethanol, and then in Dry in an oven at 60°C for 6 hours to obtain a copper oxide nanoshuttle sample. The morphology of copper oxide was analyzed by transmission electron microscopy (TEM). Figure 5 It can be seen that its morphology is nanoshuttle.

Description

technical field [0001] The invention relates to a method for preparing a high specific capacity shuttle-shaped copper oxide electrode material, which belongs to the field of metal oxide nanometer material preparation. Background technique [0002] With the rapid development of the global economy, the depletion of fossil fuels and increasing environmental pollution, there is an urgent need for efficient, clean and sustainable energy sources, as well as new technologies related to energy conversion and storage. Therefore, supercapacitors (also known as electrochemical capacitors) are characterized by high power, faster response time and a near-infinite life cycle with reasonable energy density, which is the advantage of both traditional dielectric capacitance and energy storage batteries. electrical energy storage device. The current development direction of supercapacitors should focus on the use of environmentally friendly materials, increased power and energy density, and ...
