Electrolyte‐Dependent Sodium Plating for Anode‐Free Na‐Ion Batteries Studied by Operando Optical Microscopy

open access: yesAdvanced Science, EarlyView.
Anode‐free sodium‐ion batteries are examined using carbonate‐, glyme‐, and localized high‐concentration electrolytes. Distinct sodium plating morphologies are identified by operando optical microscopy, revealing uniform crystalline deposition for glyme‐based systems.
