Enabling Low‐Temperature Fast‐Charging Anode‐Free Sodium Metal Batteries: A Synergistic Design of Electrolyte Solvation and Current Collector Interface
Anode‐free sodium metal batteries (AFSMBs) promise ultrahigh energy density (>350 Wh kg −1 ) and low cost, yet their operation under low‐temperature and fast‐charging conditions is critically hindered by limited sodium inventory and sluggish interfacial kinetics. This conflict creates a “stability paradox”: the p...
