Abstract
Battery systems and methods for accelerating ion diffusion in polymer electrolyte materials. The application of oscillating electric fields is used to improve the ionic transport properties of polymer electrolytes by reducing the apparent hopping barrier of the lithium ions within the electrolyte material. Polymer-electrolyte-based battery cells exhibiting enhanced ion mobility due to the application of such oscillating electric fields.
