Supercapacitors are widely used in electric and hybrid vehicles, wind farm and low-power equipment
due to their high specific power density and huge number of charge–discharge cycles. Waste supercapacitors
should be recycled according to EU directive 2002/96/EC on waste electric and electronic equipment.
This paper describes a recycling approach for end-of-life supercapacitors based on shredding
and mild thermal treatment.
