Embodiment 1
[0022] A method for recycling waste cigarette butts, the specific steps are as follows:
[0023] Recycling waste cigarette butts, photo as figure 1 As shown, the waste cigarette butts were shredded and placed in a tube furnace under N 2 At 5°C·min under atmosphere -1 The heating rate was increased to 800°C, and roasted at a constant temperature for 1 hour. After cooling to room temperature, the roasted product was taken out, washed with dilute hydrochloric acid to remove inorganic salts such as ash, then washed with distilled water until neutral, and vacuum-dried to obtain the waste cigarette butt negative electrode material; then the obtained waste cigarette butt negative electrode material is ground into powder, and tested by SEM, the results are as follows figure 2 shown by figure 2 It can be seen that the obtained waste cigarette butt negative electrode material powder presents irregular particle morphology, the particle size is less than 8 μm, and many small particle...
Embodiment 2
[0025] A method for recycling waste cigarette butts, the specific steps are as follows:
[0026] The recycled waste cigarette butts were shredded and placed in a tube furnace under N 2 Atmosphere at 3°C·min -1 The heating rate was raised to 600°C, and roasted at a constant temperature for 2 hours. After cooling to room temperature, the roasted product was taken out, washed with dilute hydrochloric acid to remove inorganic salts such as ash, and then washed with distilled water until it was neutral. After vacuum drying, the waste cigarette butt negative electrode was obtained. material; then the obtained waste cigarette butt anode material is ground into powder, and its XRD is tested, such as image 3 shown by image 3 It can be seen that the diffraction peaks corresponding to the graphite crystal planes (002) and (101) appeared around 2θ=23° and 2θ=43°, indicating that the prepared waste cigarette butt anode material was amorphous carbon.
Embodiment 3
[0028] A method for recycling waste cigarette butts, the specific steps are as follows:
[0029] The recycled waste cigarette butts were shredded and placed in a tube furnace under N 2 At 5°C·min under atmosphere -1 The heating rate was increased to 700°C, and roasted at a constant temperature for 1 hour. After cooling to room temperature, the roasted product was taken out, washed with dilute hydrochloric acid to remove inorganic salts such as ash, then washed with distilled water until neutral, and vacuum-dried to obtain the negative electrode of waste cigarette butts material; then the gained waste cigarette butt anode material is ground into powder, by testing the Raman spectrum, such as Figure 4 shown by Figure 4 It can be seen that at a wave number of 1345 cm -1 The D peak at , indicating the presence of a chaotic graphite structure; at a wavenumber of 1598 cm -1 The G peak that appears at the place corresponds to the ideal graphite structure; the intensity ratio of...
