Engineers have unlocked a new class of supercapacitor material that could rival traditional batteries in energy while ...

Materials engineers at Monash University in Australia have devised a method of producing graphene supercapacitors that have the same energy density as the lead-acid battery under your car's hood. Not ...

Supercapacitors—also known as ultracapacitors—store energy similarly to batteries. However, they dispense power extremely quickly instead of over hours. As high-power-density energy storage systems, ...

Modern life relies on electricity and electrical devices, from cars and buses to phones and laptops, to the electrical systems in homes. Behind many of these devices is a type of energy storage device ...

Left) Schematic illustration of a composite of CNTs and PANIs. It shows that the covalently bonded PANIs are evenly distributed among the CNTs and that each PANI can act as a nanoscale cell. (Right) ...
