Graphene And Liquid Salt To Double The Energy Storage Of Supercapacitors

Graphene And Liquid Salt To Double The Energy Storage Of Supercapacitors - Energy Featured Graphene

Researchers at the University of Waterloo managed to significantly improve supercapacitors, by combining with an oily liquid salt in the supercapacitors’ electrodes.

The researchers explained that the liquid salt serves as a spacer to separate the thin graphene sheets, preventing them from stacking. That dramatically increases their exposed surface area, a key to maximizing energy-storage capacity. At the same time, the liquid salt doubles as the electrolyte needed to actually store electrical charge, minimizing the size and weight of the supercapacitor.

The innovation also uses a detergent to reduce the size of the droplets of oily salt – which is combined with water in an emulsion – to just a few billionths of a metre, improving their coating action. The detergent also functions like chemical Velcro to make the droplets stick to the graphene.
