Cronau, Marvin published the artcileThickness-Dependent Impedance of Composite Battery Electrodes Containing Ionic Liquid-Based Electrolytes, COA of Formula: C10H22O5, the main research area is lithium ion battery thickness charge transfer resistance current density.
Lithium-ion battery models often neglect the salt concentration polarization inside the electrolyte-filled pores of the composite electrodes. However, this concentration polarization causes a significant impedance, in particular in the case of electrolytes with low Li+ transference numbers Here, we analyze in detail measured and calculated impedance spectra of composite electrodes containing a solvate ionic liquid-based electrolyte and an ionic liquid-based electrolyte, resp., in comparison to a conventional carbonate-based electrolyte. For calculating spectra, we use a recently published model by Huang and Zhang. We find that the impedance at 10-4 Hz, which is relevant for battery cycling rates around 1 C to 2 C, increases in the order carbonate-based electrolyte
