In this themed collection we showcase cutting-edge research and perspectives on designing nanostructured polymers with charge transport properties from experimental, computational, and theoretical research groups.
Such materials are critical as solid polymer electrolytes for lithium metal batteries. These mixed conducting materials can serve as binder materials to enable reversible redox reactions in electrodes. Overall, nanostructured polymeric materials are versatile materials that can be designed to achieve multi-functionality encompassing mechanical strength, charge transport (ion and/or electron) and redox-activity.
