Understanding Ionic Conductivity in Crystalline Polymer Electrolytes

STRUCTURAL AND IONIC CONDUCTIVITYSTUDIES ONPLASTICIZED PAN-SODIUM FLUORIDE POLYMER ELECTROLYTES FOR ELECTROCHEMICAL CELL APPLICATIONS

Ion conducting gel polymer electrolytes based on poly acrylonitrle (PAN) complexed with different weight percent ratios of Sodium Fluoride (NaF) salt were prepared by using solution cast technique. Structural characterization was performed using X-ray diffraction (XRD) technique and Fourier transforms infrared (FTIR) spectroscope technique. From the X-rd results increase in amorphous phase with...

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...

Use of ionic liquids for pi-conjugated polymer electrochemical devices.

pi-Conjugated polymers that are electrochemically cycled in ionic liquids have enhanced lifetimes without failure (up to 1 million cycles) and fast cycle switching speeds (100 ms). We report results for electrochemical mechanical actuators, electrochromic windows, and numeric displays made from three types of pi-conjugated polymers: polyaniline, polypyrrole, and polythiophene. Experiments were ...
