Ultra‐Long and Rapid Operating Sodium Metal Batteries Enabled by Multifunctional Polarizable Interface Stabilizer (Adv. Energy Mater. 33/2024)

Sodium Metal Batteries In article 2304504, Won‐Hee Ryu and co‐workers illustrate the potential to realize ultra‐long and rapid operation in Na‐metal batteries by introducing vinylpyrrolidone (VP) as a polarizable molecular dipole electrolyte additive. The VP molecules offer a surface‐flattening effect by controlling the growth direction of Na deposition and strengthen the solid electrolyte interface layer with a durable component, thereby achieving exceptional cycle performance even under high current density operation.
