(2023). Recycling of Plastic Wastes for the Mass Production of Yolk−Shell-Nanostructured Co3O4@C for Lithium-Ion Batteries. ACS Applied Nano Materials, 6(2), pp. 1171-1180. doi: 10.1021/acsanm.2c04757.https://hdl.handle.net/20.500.12539/1858Facing the ever-increasing production of municipal plastics, great efforts have been made to recycle plastic waste into high value-added products. As the main components of plastic wastes, PP, PE and PS are uncharred polymers, which are hard to be carbonized under normal conditions. To address this issue, transition metal catalysts (Co3O4) were introduced to carbonize the plastic waste with high carbon yields. Herein, the mixed waste plastics (PP/PE/PS) were carbonized into yolk-shell structured Co3O4@carbon nanomaterials with high yield of 49 wt%. A high capacity of 1066 mAh g-1 at 0.1 A g-1 after 100 cycles in lithium-ion batteries. Moreover, the galvanostatic intermittent titration technique (GITT) results estimated that the YSS Co3O4@C possessed a higher Li+ diffusion coefficient, ensuring an improved cycling stability and rate performance. The present strategy not only provides a potential approach for recycling waste plastics into high-value carbon materials, but also shows the possibility for the mass production of high-performance nanosized anode materials for LIBs in a commercial way.enUznanie autorstwa 3.0 Polskawaste plasticface maskyolk−shell structureCo3O4/C compositelithium-ion batteryDyscyplina::Nauki inżynieryjno-technicznePreprinthttps://doi.org/10.1021/acsanm.2c04757
