Ultrafast Lithium between two graphene layers
Research report (imported) 2017 - Max Planck Institute for Solid State Research
In analogy to lithium-ion technology, bilayer graphene is employed as an electrode in an electrochemical cell for the first time. An innovative cell design allows for the application of electronic transport methods known from the field of nanostructures and low-dimensional systems. This unusual combination offers unprecedented direct access to the motion of lithium-ions that may be reversibly inserted in between the two carbon sheets of bilayer graphene. An ionic mobility much higher than in bulk graphite can thus be revealed.
