Abstract

Abstract : Dynamic Ionic Transport In article number 2204052, Hochun Lee, Yong Min Lee, Hongkyung Lee, and co‐workers demonstrate Li dendrite suppression with 1‐μm long, magnetic nanospinbar (NSB) dispersed electrolytes. Spatially distributed NSBs within various electrolytes can generate mesoscale turbulence actuated by an external rotating magnetic field. NSB‐assisted dynamic Li + transfer enables fast and uniform seeding of Li nuclei, inhibiting dendritic Li electroplating, thereby leading to stable cycling of Li‐metal batteries. Dynamic ionic transfer via NSB colloids opens new possibilities for out of mass‐transfer‐limit in various electrochemical systems.
