Title: Dendrite-suppressing ion-conductors from aramid nanofibers withstanding extreme battery conditions

Abstract

Ion conducting membranes based on aramid nanofibers (ANFs) can be prepared using layer-by-layer assembly, sol-gel processing, evaporation, spin coating, doctor blading, or other methods. Porosity is controlled through choice of additives and processing.
