New paper published in Journal of Materials Chemistry A on the role of carbon additive properties for antimony conversion batteries

New paper published in Journal of Materials Chemistry A on the vital role of the properties of carbon as the conductive additive in Sb-conversion sodium-ion batteries. The homogeneity, morphology, size, and other properties of the carbon additive enable (or defy) high electrochemical performance and stability.

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 and Technology)  and experimental work from our team.

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 some sub-1-nm pores. This work was done in collaboration with Guang Feng (Huazhong University of Science and Technology) and Yury Gogotsi (Drexel University).

New paper published in Electrochimica Acta on electrolytes for 2.8 V hybrid supercapacitors

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).
