摘要：

The relationship between Li(I) transport property and the limiting current density was investigated in N-methyl-N-propylpyrrolidinium bis(trifluoromethylsulfonyl)amide (P13TFSA) at 30 degrees C. The limiting current density in a LiTFSA/P13TFSA binary ionic liquid electrolyte was evaluated by chronoamperometry for a symmetric cell of Li vertical bar ionic liquid vertical bar Li, where the ionic liquid was incorporated in a porous polyethylene separator that was sandwiched between two Li electrodes. The diffusion process of Li(I) in the ionic liquid dominates the limiting current density in the cell. In addition to the Li(I) transport property of the electrolyte, the porosity and tortuosity of the separator has a significant effect on the limiting current density.
