New paper published in Electrochimica Acta on the influence and best-choice of electrolytes (organic / ionic liquid) when using hybrid supercapacitors operated at 2.8 V. The datae xplore below-ambient and above-ambient temperatures and demonstrates 3-methoxypropionitrile and mixed organic electrolytes as promising ones for specific performance regimes.

New paper published in Desalination on the use of ion exchange membranes for capacitive deionization
New paper published in Desalination. The work with the title “Polymer ion-exchange membranes for capacitive deionization of aqueous media with low and high salt concentration” investigates the desalination performance of ion-exchange membranes coated directly onto carbon electrodes with free-standing ion-exchange membranes at high and low molar strenght. The data show that MCDI enables reasonable desalination even of highly concentrated solutions. The work was done in collaboration with Markus Gallei (Saarland University).
