Zinc Stannate as anode and Pyrrolidinium-Based Room Temperature Ionic Liquid as electrolyte for Lithium-ion Cells

With the aim to design safer batteries, pyrrolidinium-based room temperature ionic liquids (RTIL) have been used as electrolytes in Li-ion batteries using zinc stannate as the anodic material. The lithium diffusion coefficients were calculated using Electrochemical Impedance Spectroscopy (EIS) data and were 2.37 x 10(-12) cm(2)s(-1) for MPPyrTFSI and 1.29 x 10(-12) cm(2)s(-1) for BMPyrTFSI. The performance of the device strongly depended on the cation chemical structure, yielding different specific capacity values of 306.3 mAhg(-1) for BMPyrTFSI and 269.2 mAhg(-1) for MPPyrTFSI.

Automated summary

In the quest for safer batteries, pyrrolidinium-based room temperature ionic liquids (RTIL) have been utilized as electrolytes in Li-ion batteries using zinc stannate as the anodic material. The lithium diffusion coefficients, performance, and specific capacity strongly depended on the cation chemical structure in this system.
