#Graphene"Decorated"With Lithium Becomes a Superconductor Graphene is a conductor unlike anything seen before.
nobody had been able to make graphene behave as a superconductor, until now. An international research team from Canada and Germany has been able to demonstrate that graphene can be made to behave as a superconductor
when it doped with lithium atoms. The researchers believe that this new property could lead to a new generation of superconducting nanoscale devices.
Superconductors are materials that conduct electricity without resistance and without dissipating energy. In ordinary materials, electrons repel each other,
but in superconductors the electrons form pairs known as Cooper pairs, which together flow through the material without resistance.
Graphene is not naturally a superconductor, and neither is its three-dimensional sourceraphite. However, it was demonstrated a decade ago that graphite could be induced into behaving like a superconductor.
If it possible with graphite it should be with graphene, right? Other research groups believed
The key observation was increased that this number of coupled pairs led to superconductivity, which the researchers measured by identifying an energy gap between the material's conducting and nonconducting electrons.

These batteries typically contain cathode particles through which the electrons flow, an action that enables the battery to charge.
These cathode particles are composed typically of lithium iron phosphate or lithium cobalt oxide, mixed together with carbon black,
Ultimately, the rate at which a cathode particle charges depends on how well it is connected to carbon black particles,
"Li said that by upping the percentage of carbon black as high as 20 percent in some experiments they found that the cathode particles charged more quickly
Increasing the percentage of carbon black decreased the amount of cathode particles available to hold a charge.
