A new type of nanopolypyrrole/organically modified montmorillonite-ionic liquid gel polymer electrolyte (ppy/OMMT-ILGPE) is prepared based on nanopolypyrrole/organically modified montmorillonite (ppy/OMMT), N-butyl-N- methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PP14TFSI), lithium-bis(trifluoromethanesulfonyl) (LiTFSI), polyvinylidene difluoride (PVDF), methyl methacrylate (MMA), and benzoyl peroxide (BPO) by an in situ method. The effect of nano-ppy/OMMT on the physical and electrochemical properties of an ionic liquid gel polymer electrolyte is demonstrated. The results show that nano-ppy/OMMT-ILGPE has a porous structure with a large surface area, and the diameter of the pores on the surface is approximately 1-2 μm. The Li+ transference number of 0.72 is achieved, and the ionic conductivity reaches up to 1.2 × 10−3 S/cm at room temperature. Nano-ppy/OMMT-ILGPE has good thermal stability and mechanical properties. Meanwhile, nano-ppy/OMMT-ILGPE has fine cycle performance in the Li|nano-ppy/OMMT-ILGPE|LiNi1/3Co1/3Mn1/3O2 coin cell. The good electrochemistry performance of nano-ppy/OMMT-ILGPE means that it can act as an ideal gel polymer electrolyte material for lithium ion batteries.

First Discharge Capacity

The lithium ionic conductivity of Poly (acrylonitrile) (PAN) gel polymer electrolyte with PC/EC was found to be about 1.3 x 10-3S/cm at room temperature. The discharge curve of Li/ PAN (PC+EC)/S battery showed only one plateau region, which is different from that using PVdF(TEGDME) gel polymer electrolyte. Also, the first discharge capacity was 556mAh/g-sulfur in Li/S battery using PAN (PC+EC) gel electrolyte at room temperature.
