This symposium will focus on key issues limiting the charge transport in materials for electrochemical energy storage technologies. The pressing need for devices that are safer, lighter, cost-effective, and also able to sustain increased charge and discharge rates has led to many recent developments in both electrolytes and electrodes for batteries and capacitors. In many cases, the rate of ion or electron transport through the electrolyte, electrodes, or the interfaces between is the limiting metric for device performance. The success of beyond Li-ion devices made from more earth abundant materials, including Na-ion, Mg-ion, and Al-ion platforms, is dependent on efficient transport of these species through the electrolytes and electrodes. Submissions that report on materials development or advances in the characterization or modeling tools to reveal charge transport mechanisms and structure-property relationships are encouraged.
