Plastic bottles turned into electric vehicle battery material

Penn State researchers converted waste PET plastic bottles into synthetic graphite by blending shredded PET with 2.5% graphene oxide by weight and applying heat treatment, producing crystallite dimensions that exceeded those of natural graphite without metal catalysts. The metal-free process reduces post-processing steps needed to achieve battery-grade purity and could supply graphitic carbon for lithium-ion anodes and hard carbon for sodium-ion batteries from a single plastic waste feedstock.
