| Abstract Scope |
The global electrochemical energy storage market ranging from electric vehicles and personal electronics to grid storage and defense applications demands the development of new materials for sustainable fabrication of rechargeable batteries and supercapacitors. I will describe recent advancements in upcycling polyethylene terephthalate (PET) waste and glass waste bottles into active electrode materials for energy storage. An interconnected silicon-network is directly derived from glass-bottles via magnesiothermic-reduction. For PET plastic-waste, materials are dissolved in a mixture of trifluoroacetic acid and dichloromethane, followed by carbonization under an argon/hydrogen atmosphere. Electrodes derived from PET are employed in supercapacitors and Li-ion battery anodes. Glass bottles utilizing magnesiothermic-reduction without pre-leaching offers an environmentally-benign and energy-saving route to prepare silica-source materials, employed in fabricating Li-ion battery anodes. Both conversion processes for plastic and glass waste are highly scalable with environmental and economic advantages, and could provide the means for achieving a circular economy in energy storage technologies. |
