Electrolyte Engineering Assisted by Pseudo‐Diluent for Stable and High‐Voltage Sodium Metal Batteries
Practical sodium metal batteries (SMBs) remain hindered by Na dendritic growth and limited cathode areal loading (<1 mAh cm−2). Typical localized high concentration electrolytes (LHCEs) can offer wide electrochemical windows and improved physical properties, while critical challenges persist: (a) sluggish Na+ interfaci...
