Study of ionic conductivity today encompasses not only traditional crystalline fast ion conductorsbut also various types of structurally disordered materials such as glasses, ionic melts, polymerelectrolytes and ionic liquids - both simple and confined in supramolecular networks. Amongstvarious models that were developed in the past three decades, the model MIGRATION Conceptbased on jump-relaxation of ions has proved to be the most versatile one in modelingconductivity spectra - extracting length and time scales relevant to ion dynamics in systemsunder study. In the current project, I propose to use MIGRATION Concept to model ionicconductivities and permittivities in mixed network former glasses, ionic liquids and ionogels.Results such as cage length and typical time scales of localized diffusion will help engineer ionconducting materials for better device applications. This project also aims at knowledge transferand development of an open-resource software of the model.
