AB - Disposable masks manufactured in response to the COVID-19 pandemic have caused environmental problems due to improper disposal methods such as landfilling or incineration. To mitigate environmental pollution, we suggest a new process for recycling these disposable masks for ultimate application as a conductive material in lithium-ion batteries (LIBs). In our work, the masks were chemically processed via amine functionalization and sulfonation, followed by carbonization in a tube furnace in the Ar atmosphere. The residual weight percentages, as evaluated by thermogravimetric analysis (TGA), of the chemically modified masks were 30.6% (600 °C, C-600), 24.5% (750 °C, C-750), and 24.1% (900 °C, C-900), respectively, thereby demonstrating the possibility of using our proposed method to recycle masks intended for disposal. The electrochemical performance of the fabricated carbonized materials was assessed by fabricating silicon/graphite (20:80) anodes incorporating these materials as additives for use in LIBs. Using a coin-type half-cell system, cells with the aforementioned carbonized materials exhibited initial capacities of 553 mAh/g, 607 mAh/g, and 571 mAh/g, respectively, which are comparable to those of commercial Super P (591 mAh/g). Cell cycled at the rate of 0.33 C with C-600, C-750, and C-900 as additives demonstrated capacity retention of 53.2%, 47.4%, and 51.1%, respectively, compared with that of Super P (48.3%). In addition, when cycled at rates from 0.2 to 5 C, the cells with anodes containing the respective additives exhibited rate capabilities similar to those of Super P. These results might be attributable to the unique surface properties and morphologies of the carbonized materials derived from the new recycling procedure, such as the size and number of heteroatoms on the surface.
