제목 Electrochemical properties of Li-Ion Battery Anode Materials Recycled using Waste Plastics
초록  Plastics commonly found around us are cheap and light, therefore use of plastics are indispensable in our daily life. However, too heavy use of plastics causes the disposal issue of plastics, resulting in environmental problems in the earth. The landfilling process of plastics is the simplest way to dispose plastic waste, but plastics remain undecomposed in the ground and last for a long time. When incineration process is carried out, plastics burn, also generating toxic substances. Among various disposal process of plastics, recycling of plastics is of great attention since recycling of plastics restricts generation of waste and harmful byproducts. Furthermore, recycled plastics can be another resources for the industry. Recently, the anode material for Li-ion batteries (LIBs) that are recycled from the plastics have been reported.
Herein, we recycled plastics and produced the anode materials for LiBs. We recycled HDPE and LDPE plastic wastes, a kind of thermoplastic material. By sulfonation during hydrothermal reaction, thermal stability of plastics was improved. Then, plastics were heat treated in the inert atmosphere, by which plastics could be carbonized. SEM, XRD, Raman, and XPS were analysed to identify the physicochemical nature of obtained carbon, which indicated that carbonization of plastic wasted produced soft carbon. The electrochemical performance of as-prepared soft carbon was investigated to study energy storage capability for LIBs. Our work demonstrated that the soft carbon recycled from plastic wastes can work as the anode material.
