Synthetic graphite is still the standard anode material for lithium ion battery industry. Herein, we introduce a scalable, recycled Polyethylene Terephthalate (PET)–derived graphite anode for lithium-ion battery. PET-derived anodes were obtained through electrospinning process. Formation of graphite tubes with diameter of 0.5 – 2 micrometers was confirmed through Raman analysis and Scanning Electron Microscopy (SEM) images respectively. Additionally, X-ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and Brunauer-Emmett-Teller (BET) analysis were applied as well. Electrochemical properties of PET-derived graphite anodes were tested through Galvanostatic Cycling with Potential Limitation (GCPL), Galvanostatic Intermittent Titration Technique (GITT), Electrochemical Impedance Spectroscopy (EIS) and Constant Voltage (CV). Obtained PET-derived carbons show high surface area with good lithium diffusivity and capacity of 264 mAh/g after 500 cycles. The study provides a novel pathway to fabricate high capacity energy storage device from recycled waste plastic.
