New paper published in Sustainable Energy & Fuels on the unexpected permselectivity of sub-1-nm pores

New paper published in Sustainable Energy & Fuels on the expected permselectivity of sub-nanometer pores of activated carbon. This effect enables membrane-free use of carbon electrodes for seawater desalination even at high molar strength, such as presented by seawater. This complementary work brings together modeling from the group of Guang Feng (Huazhong University of Science […]

New paper published in ACS Nano on ion structure formation of supercapacitors

New paper published in ACS Nano on ionic structure transition within carbon nanopores that enhance the charge/discharge kinetics of electrical double-layer capacitors. Different from the traditional view that a smaller pore results in slower charging, a non-monotonic relation is found between the charging rate and pore size, in which the charging process is accelerated in […]

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 […]

New paper published in Journal of Power Sources on electrospun vanadium sulfide fiber mat electrodes

New paper published in Journal of Power Sources on the synthesis of vanadium sulfide / carbon electrospun, free-standing, binder-free electrodes for lithium-ion battery application. This work was in collaboration with the Max-Planck Institute for Iron Research (Christina Scheu) and the Leibniz Institute for Plasma Science and Technology (Angela Kruth).
