[0042] A second aspect of the present invention provides a method for preparing a wearable and rechargeable fabric, the method comprising the following steps: supporting a positive electrode sheet and a negative electrode sheet on the same fabric substrate to obtain the fabric; wherein, the positive electrode The sheet includes a positive electrode material, and the positive electrode material is a conductive polymer material; the negative electrode sheet includes a negative electrode material, and the negative electrode material is a metal material; the conductive polymer material is selected from polyaniline or polypyrrole.
[0043] In some embodiments of the present invention, the preparation method of the wearable and rechargeable fabric includes the following steps: directly supporting the conductive polymer material and the metal material on the same fabric substrate to obtain the fabric .
[0044] In some embodiments of the present invention, preferably, each of the pos...
Embodiment 1
[0064] (1) Preparation of zinc / carbon cloth negative electrode sheet:
[0065] First, the carbon cloth was ultrasonically cleaned with a mixed solution containing water, ethanol and acetone for 30 minutes, then ultrasonically cleaned with deionized water for 15 minutes, repeated several times, and then cleaned and dried. Next, in a hydrochloric acid solution containing 0.5M, a saturated calomel electrode was used as the reference electrode, Pt was used as the counter electrode, and carbon cloth was used as the working electrode, and a constant voltage of 5V was applied through the electrochemical workstation for 3 min, and then rinsed with deionized water after taking it out. clean. Then, in a solution containing 0.5M ZnSO 4 , 1M NaSO 4 and 0.3M H 3 BO 3 In the mixed solution, Ag / AgCl was used as the reference electrode, Pt was used as the counter electrode, and the carbon cloth was used as the working electrode. A constant current of -40 mA was applied through the electro...
