US researchers have developed a supercapacitor technology that can be deposited onto plastic film to make flexible capacitors, and silicon die for in-package energy storage. Specific power delivery is higher than traditional supercapacitors.
Electrical performance is virtually unchanged after thousands of flexing cycles.
Developed by Maher El-Kady and Richard Kaner at the University of California, Los Angeles, the capacitors rely on an expanded form of graphene that has been dubbed laser-scribed graphene (LSG), a novel planar structure, and an ionic liquid electrolyte.
Traditional supercapacitors have two ion-porous electrodes separated by a porous electrically-insulating separator. The whole assembly is soaked in an electrolyte.
