New paper published on ion transport kinetics in carbon nanopores in Nature Communications

New paper published in Nature Communications on the ion transport in carbon nanopores. The charge storage kinetics (and discharge process) of ionic liquid supercapacitors can significantly be enhanced when employing non-conventional charge/discharge profiles – and: slower is faster! This work was done in collaboration with colleagues from Stuttgart (both MPI for Intelligent Systems and University of Stuttgart), Slavko Kondrat (Institute of Physical Chemistry, Poland), and Layla Mehdi (University of Liverpool, UK).
