Molecular Dynamics Simulation of Diffusivity and Mobility of Ionic Charge Carriers in Model Battery Polymers

POSTER

Abstract

Molecular dynamics simulations of poly(ethylene-co-acrylic acid) monomers doped with Lithium ions were conducted using LAMMPS. The drift velocity of the ions resulting from a range of static electric fields were used to compute the ionic mobility. The frequency dependent mobility was also studied by using oscillatory electric fields.
