Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration

Advanced Science, EarlyView.
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

Sodiophilic Na3Sb Framework‐Regulated Sodium Deposition and Interphase Evolution for Dendrite‐Free and Long‐Life Sodium Metal Batteries

Advanced Science, EarlyView.
An interconnected sodiophilic Na3Sb framework embedded within a metallic Na matrix enables uniform Na deposition by homogenizing Na+ flux and providing abundant nucleation sites. Simultaneously, the regulated interface promotes the formation of a stable, NaF‐rich inorganic interphase, collectively suppressing dendrite growth and enabling highly ...

Resolving Oxidative and Corrosive Calendar‐Aging via Electrolyte Engineering for Stable Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
A weakly solvating ether solvent, 1,2‐dimethoxypropane (DMP), is proposed for use in localized high‐concentration electrolytes (LHCEs) for lithium metal batteries (LMBs). These DMP‐based LHCEs simultaneously suppress lithium metal corrosion and cathode degradation—two interrelated processes that accelerate calendar aging of LMBs.

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.
