A supercapacitor is a double-layer capacitor that has very high capacitance but low voltage limits. Supercapacitors store more energy than electrolytic capacitors and they are rated in farads (F).

Ultrahigh energy storage density and efficiency in AgNbO 3-based ceramics by percolating interaction between antipolar regions and defect pairs A percolating interaction between antipolar regions and ...

A new material called multiscale reduced graphene oxide could mean faster charging and power delivery than traditional batteries allow. When you purchase through links on our site, we may earn an ...

Scientists have found a new way to manipulate graphene to create a substance with record-breaking energy and power density. When incorporated into energy storage devices called supercapacitors, this ...
