Background
The super capacitor has the characteristics of high charging speed, high power density and good cycle stability, becomes a potential energy storage device and becomes a bridge connecting the traditional capacitor and the lithium ion battery. However, the lower energy density is currently limiting the large-scale application of supercapacitors. Pseudo-capacitance material Bi 2 O 3 The material has the characteristics of high theoretical capacity, reversible oxidation-reduction process, wide working potential window and environmental friendliness, is considered to be a promising super-capacitor negative electrode material, and can solve the problem of low energy density. Theoretically, an ideal capacitor material should have i) a high specific surface area exposed to more electrochemically active sites; ii) excellent conductivity to accelerate electron transfer; iii) the porous structure facilitates electrolyte diffusion. However, since Bi 2 O 3 Poor conductivity and fewer electrochemically active sites on the surface result in lower actual capacitance. Currently, Bi is regulated and controlled by adding a surfactant in the preparation process 2 O 3 The microstructure and morphology of (a). However, since the surfactant is difficult to remove, a large amount of water is required to be consumed in the washing process; in addition, the residual surfactant in the sample can reduce the conductivity of the electrode, and affect the electron transfer efficiency and the rate performance of the electrode. In addition, the large discharge of the surfactant causes environmental pollution. From the above, it can be seen that Bi is currently produced by the alcoholic thermal method 2 O 3 The electrode also has the problems of poor conductivity, insufficient surface active sites, environmental pollution caused by the application of a surfactant and the like. Therefore, how to realize Bi by a new green and environment-friendly method 2 O 3 Morphology control and increased conductivity, and thusPower-up capacity has become a hotspot in research.

Adding a mixed solution of water and ethanol into the solution, and continuing magnetic stirring. Transferring the mixed solution into a 100mL reaction kettle lining, and heating for 5 hours in an oven at 160 ℃ to obtain flower-shaped Bi with high crystallinity 2 O 3 An electrode material.
Example 2:
solvothermal method for preparing flower-like Bi 2 O 3 ：
Solvothermal method for preparing flower-like Bi 2 O 3 : taking 48mL of ethylene glycol, 12mL of ethanol and 12mL of deionized water, firstly, 1.96g of bismuth nitrate (Bi (NO) 3 ) 3 ·5H 2 O) was added to a beaker containing 48mL of ethylene glycol and magnetically stirred to form a clear solution. Adding a mixed solution of water and ethanol into the solution, and continuing magnetic stirring. Transferring the mixed solution into a 100mL reaction kettle lining, and heating for 5 hours in an oven at 160 ℃ to obtain flower-shaped Bi with high crystallinity 2 O 3 An electrode material.
Example 3:
solvothermal method for preparing flower-like Bi 2 O 3 ：
Solvothermal method for preparing flower-like Bi 2 O 3 : taking 48mL of ethylene glycol and 24mL of deionized water, first, 1.96g of bismuth nitrate (Bi (NO) is added 3 ) 3 ·5H 2 O) was added to a beaker containing 48mL of ethylene glycol and magnetically stirred to form a clear solution. Adding a mixed solution of water and ethanol into the solution, and continuing magnetic stirring. Transferring the mixed solution into a 100mL reaction kettle lining, and heating for 5 hours in an oven at 160 ℃ to obtain flower-shaped Bi with high crystallinity 2 O 3 An electrode material.
Example 4:
bi prepared by adding 0mL of deionized water (i.e., all ethanol added) and 24mL of deionized water (i.e., no ethanol added) was added according to the method of example 1 2 O 3 Flower-like Bi obtained in accordance with examples 1 to 3 2 O 3 And (6) carrying out testing. The electron micrograph and X-ray diffraction pattern are shown in FIGS. 1 and 2. From FIG. 1, it can be seen that different volumes of water added to Bi 2 O 3 The morphology has a significant impact. Bi continuously increases with the water volume 2 O 3 The morphology of (A) is changed from a random structure to a flower shape. FIG. 1(a) shows that Bi is prepared in an alcoholic thermal system without adding water 2 O 3 The crystal structure is a random structure with lower crystallinity, and the surface is rough and the appearance is uneven. FIG. 1(b-d) shows Bi to which 6mL, 12mL, and 24mL of water were added 2 O 3 Morphology, from SEM picture, Bi can be seen 2 O 3 The appearance presents a uniform flower ball shape, the grain size is uniform, and the dispersibility is good. Meanwhile, it can be observed from FIG. 1(b-d) that the flower-like spherical Bi formed after adding a minute amount of water 2 O 3 Is assembled by a large number of ultrathin nanometer sheet structures. The ultrathin sheet structure is beneficial to improving Bi 2 O 3 The specific surface area of (2) increases the number of surface active sites, thereby increasing the capacitance. In addition, the sheet structure facilitates the diffusion of electrolyte ions, increasing rate performance. From the XRD pattern of FIG. 2, it can be observed that Bi is added with water 2 O 3 The increase in diffraction peak intensity of (a) indicates that a small amount of water contributes to the increase in crystallinity, which results from the fact that water accelerates the hydrolysis rate of the Bi intermediate to form large particles of Bi 2 O 3 . The high crystallinity contributes to reduction of resistance, acceleration of electron transfer efficiency, and further improvement of capacitance.
Preparation of a working electrode: mixing the above Bi 2 O 3 As an electrode active material, Bi 2 O 3 With carbon black and polyvinylidene fluoride (PVDF) according to 8: 1: 1, adding a proper amount of N-methyl pyrrolidone, and uniformly grinding in a mortar to form uniform slurry; and then uniformly coating the slurry on the surface of the carbon cloth, drying at 60 ℃, and determining the mass of the electrode active material according to the mass difference between the front mass and the rear mass of the carbon cloth.
Electrochemical performance test process:
to be coated with Bi 2 O 3 Carbon of (2)Cloth is used as a working electrode to construct a three-electrode system; before testing, firstly, electrode activation is carried out by 100 cycles of Cyclic Voltammetry (CV) in a potential window of-1V to 0V, and then 1Ag is carried out -1 Constant current charging and discharging (GCD) tests were performed at the charging and discharging current densities of (a) and the electric capacity of the electrode material was calculated from the curve discharge time. Based on the above test results, the effect of trace amounts of water on the electrochemical performance was analyzed.
The results are shown in FIG. 3, where the redox plateau of the GCD curve in FIG. 3 indicates Bi 2 O 3 Where redox reactions occur, illustrating their pseudocapacitive behavior. When 6mL of water is added, Bi 2 O 3 The electrode has the longest charge-discharge time and the current density of 1A g -1 At this time, the capacitance reaches 889F g -1 Bi without the addition of water 2 O 3 Electrode and Bi with 12mL water addition 2 O 3 Electrode, Bi with 24mL of water added 2 O 3 The charging and discharging time of the electrodes is not greatly different. Thus, Bi with 6mL of water added 2 O 3 Shows the best capacity performance, mainly due to Bi added with 6mL of water 2 O 3 Ultra-thin nanosheets appear in the electrode, and the lamellar structure improves Bi 2 O 3 The specific surface area of the capacitor increases the number of surface active sites, and further increases the capacitance.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and the present invention shall fall within the protection scope of the present invention as long as the technical effects of the present invention are achieved by the same means.
