Designing low toxic deep eutectic solvents for the green recycle of lithium-ion batteries cathodes
ChemSusChem. 2024 Feb 26:e202301953. doi: 10.1002/cssc.202301953. Online ahead of print.ABSTRACTThe Lithium-ion battery (LIB) is one of the main energy storage equipment. Its cathode material contains Li, Co, and other valuable metals. Therefore, recycling spent LIBs can reduce environmental pollution and resource waste, which is significant for sustainable development. However, traditional metallurgical methods are not environmentally friendly, with high cost and environmental toxicity. Recently, the concept of green chemistry gives rise to environmental and efficient recycling technology, which promotes the transition of...

ChemSusChem. 2024 Feb 26:e202301781. doi: 10.1002/cssc.202301781. Online ahead of print.ABSTRACTPoly(ethylene terephthalate) (PET), extensively employed in bottles, film, and fiber manufacture, has generated persistent environmental contamination due to its non-degradable nature. The resolution of this issue requires the conversion of waste PET into valuable products, often achieved through depolymerization into monomers. However, the laborious purification procedures involved in the extraction of monomers pose challenges and constraints on the complete utilization of PET. Herein, a strategy is demonstrated for the polymer...
