Microstructure Optimization of Na3SbS4/Na3Zr2Si2PO12 Composite Solid Electrolytes for Improving Cycling Stability in All‐Solid‐State Sodium Batteries

Advanced Science, EarlyView.
This research demonstrates that incorporating 10 wt.% NASICON‐type Na3Zr2Si2PO12 into Na3SbS4 sulfide electrolytes mitigates interfacial instability and structural defects. The resulting composite enhances ionic conductivity to 3.97 * 10−4 S cm−1 and reduces activation energy.
