Spent Lithium‐Ion Batteries Derived Co3O4 for Electrocatalytic Polyethylene Terephthalate Plastic Recycling

Spent lithium-ion batteries (LIBs) are an essential secondary resource containing valuable metal elements. Transforming spent LIBs into efficient catalysts through a simple process presents a promising strategy to address both metal resource scarcity and clean energy challenges. Herein, a deep eutectic solvent-assisted synthesis of Co
