Efficient upcycling of polypropylene-based waste disposable masks into hard carbons for anodes in sodium ion batteries
Journal of Industrial and Engineering Chemistry(2022)
摘要
•Disposable face masks were used as carbon precursors to propose managing the mask wastes.•Mask-derived hard carbons were synthesized using carbonization after sulfonation of masks.•Synthesized carbon powders were used as active materials of anode in sodium-ion batteries.
