Note: The string nano supercapacitor can both pass current and store energy. Copper wire and plastic nanoscale layers have been used to make this string. So far, cables and wires have been used to store electricity. But a string of light copper nanowires  can store energy in addition to transmitting electricity.
Nanowires are just like normal electrical wires except for the fact that they are much smaller. Like conventional wires, nanowires can be made from a variety of conductive and semi-conductive materials such as copper, silver, gold, iron, silicon, zinc oxide, and germanium. Nanowires can also   provideboth the possibility of current passing and energy storage in stringed nano supercapacitorsSome  silver nanowires  are  ballistic conductors . In normal conductors, electrons collide with atoms in the conductor material. This causes the electrons to slow down as they travel, creating heat as a byproduct. In ballistic conductors, electrons can pass through the conductor without collision.  Silver Nano wire  can conduct electricity effectively without generating extreme heat. As the bulk volume is reduced to the size of the nanoparticle, its melting point is lowered, because when you reduce any particle to the nanoscale, there is a significant increase in the surface-to-volume ratio.  Top -  down approach  and  bottom  -  up approach in the manufacture and propagation of nanowires   . A top-down approach literally means you take a large amount of the material you want to use for the nanowires and etch until you get the right size. A bottom-up approach is an assembly process in which smaller particles join together to form a larger structure.


Current versus  voltage   curves  provide a means of classifying the charge storage mode.  Usually, a  (nano-supercapacitor)   is independent of the potential and therefore conducts the current independent of the potential. (nano-supercapacitor)  is used to describe devices that use quasi-capacitors to store capacitive energy. This  performance shows that Faradaic electron transport plays a role in charge storage and sheds light on the properties of a particular device. (Nano supercapacitor)  It is necessary to integrate the curve of the voltage of the cell  against  the capacity and normalize it with the mass or volume of the active material. Graphically, it is the area under the voltage  versus  specific capacitance curve. By considering a ratio of the areas under the discharge and charge curves, the energy efficiency of the device can be calculated - for a supercapacitor it should be close to 100%.


Conclusion : 

The stringed nano supercapacitor has the possibility of both current passing and energy storage. Copper wire and plastic nanoscale layers have been used to make this string. So far, cables and wires have been used to store electricity. But a string of light copper nanowires  can store energy in addition to transmitting electricity.
