الملخص EN

This research paper as an article investigates electrochemical performance of poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-co-HFP) flexible nanocomposite polymer electrolytes which have been prepared successfully with incorporation of zinc oxide (ZnO) nanofiller.

First, nanofillers are incorporated in a polymer matrix to form the flexible nanocomposite PVdF-co-HFP polymer membranes (PI-CMPM), and it is obtained by phase inversion technique.

Contact angles of PI-CMPM have achieved a maximum of 136°.

After this procedure, it has been activated by using a 1.0 M LiClO4 containing of DMC/EC (1 : 1 v/v ratio) electrolyte solution to get flexible nanocomposite polymer electrolytes (PI-CMPE).

The optimized PI-CMPM has increased the electrolyte uptake by 150%.

It reaches the maximum ionic conductivity value of 2.47×10−3 S cm−1 at room temperature.

Optimized PI-CMPE achieved a maximum transference number of 0.61, which may be further evidence for the ability to fabricate high-performance lithium ion polymer batteries.
