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 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.
