Super Capacitors get more energy




Australian researchers have an alternative battery technology made a lot more useful. Their so-called super capacitors have a much higher energy density than similar prototypes had so far.

Super Capacitors similar in many ways to regular capacitors, which can be charged and their cargo can donate again. However, the super-capacitors are much larger, and therefore can hold more charge and dispensing, and thus be used as a temporary energy storage, similar to a battery. The main advantage of such super capacitors above regular batteries is its extremely rapid charge and discharge time: charging would take only a few seconds.

However, Super Capacitors have before they can be used in consumer electronics, used a big disadvantage: they must be very large in order to keep meaningful loads. On average they have an energy density of five to eight watt-hours per liter, far too few to serve. As a battery in a laptop Researchers from the Australian Monash University, however, a method developed to improve the energy density of their super capacitors an order of magnitude: they get 60 watt-hours per liter.

Grafeen voor supercondensators The super-capacitors of the Monash staff are made up of layers of graphene as an electrode, but the trick of Australians in the electrolyte. That is not only used to conduct electricity, but also to keep. The layers of graphene from each other This allows the layers of graphene precisely very densely packed, without large gaps. These dense crowding ensures greater energy density.

As a bonus could be. Super capacitors according to a simple process that seems to make paper produced That would mean that they can be. Batteries made widely According to the researchers, they are “almost” to the step from lab to commercial production of their super capacitors.
