Inorganic‐Directed Charge Delocalization Channels: Boosting Uniform Charge Distribution and Rapid Na+ Transport for Solid‐State Sodium Metal Batteries

Carbon Energy, EarlyView.
This work develops a PM@PN composite solid electrolyte via inorganic‐induced organic molecular reconstruction. It constructs continuous interfacial ion superhighways, enables uniform Na+ deposition, and significantly enhances ionic conductivity and electrochemical stability for all‐solid‐state sodium metal batteries.

Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

Carbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...
