A General Approach towards Carbonization of Plastic Wastes into Well-designed 3D Porous Carbon Framework for Superstable Lithium Ion Batteries

Abstract

Due to the ever-increasing plastic waste spurred serious environmental concern, it is highly desirable to recycle it into high-value-added products, such as carbon nanomaterials. However, the traditional catalytic carbonization of hydrocarbon polymers is severely prohibited by the complex of real-world plastic waste due to the existence of halogen-containing polymers. In this contribution, through a universal combined template based on magnesium oxide and iron(III) acetylacetonate (Fe(acac)3), a three-dimensional hollow carbon sphere/porous carbon flake hybrid nanostructure is prepared from carbonization of plastic waste with high yields (>70 wt%). This approach is not only suitable for hydrocarbon polymers, but also halogen-containing polymers. Interestingly, the obtained advanced carbon framework exhibits excellent performance in the lithium-ion battery (802 mAh/g after 500 cycles at 0.5 A/g). The present research paves a new avenue to upcycle plastic waste into a high value-added product.
