Embodiment 1
[0039] This embodiment provides a zinc ion battery and a preparation method thereof, specifically comprising:
[0040] Preparation of carbon nanotubes: The spinnable carbon nanotube array grown by vapor deposition (CVD) is fixed on a rotatable sample stage, and a carbon nanotube film with a width of 12mm is continuously pulled out from the edge of the array, and twisted to form fibers. Then it is collected on a rotating roller, and the carbon nanotubes are spun into continuous long fibers; wherein, the twist angle of the fiber collection is 20°, and the diameter of the long carbon nanotube fibers is 100 μm, such as Figure 5 shown;
[0041] Preparation of conductive polymer / carbon nanotube composite fibers: place carbon nanotube long fibers in sulfuric acid aqueous solution containing aniline monomer, and add potassium persulfate at 0°C to chemically oxidize and polymerize aniline on the fiber surface to obtain conductive polymer matter / carbon nanotube composite long-fiber elec...
Embodiment 2
[0046] This embodiment provides a zinc ion battery and a preparation method thereof. The difference from Embodiment 1 lies in the material of the substrate. The substrate of this embodiment uses polydimethylsiloxane.
Embodiment 3
[0048] This embodiment provides a zinc ion battery and a preparation method thereof. The difference from Embodiment 1 lies in the material of the substrate, which is polyurethane in this embodiment.
