Understanding Ionic Conductivity in Crystalline Polymer Electrolytes

Ionic conductivity enhancement of polymer electrolytes with ceramic nanowire fillers.

Solid-state electrolytes provide substantial improvements to safety and electrochemical stability in lithium-ion batteries when compared with conventional liquid electrolytes, which makes them a promising alternative technology for next-generation high-energy batteries. Currently, the low mobility of lithium ions in solid electrolytes limits their practical application. The ongoing research ove...

A Computer Simulation Study of Ionic Conductivity in Polymer Electrolytes

In this paper we present a computer simulation study of ionic conductivity in solid polymeric electrolytes. The multiphase nature of the material is taken into account. The polymer is represented by a regular lattice whose sites represent either crystalline or amorphous regions with the charge carrier performing a random walk. Different waiting times are assigned to sites corresponding to the d...

FTIR and Ionic Conductivity Studies on PMMA based Gel Polymer Electrolytes

This article deals about the preparation and characterization of potassium, magnesium and ammonium ion conducting PMMA based gel polymer electrolytes. The gel polymer electrolytes were prepared by solution cast method. The formation polymer complex of ionic salts and PMMA were confirmed by FTIR. The ionic conductivities were measured by impedance spectroscopy at room temperature. It was found t...
