Wetting Interactions Between Porous Carbon Hosts and Liquid Sodium‐Potassium Alloys Toward Their Use in Negative Electrodes of Alkali‐Metal Batteries (Adv. Funct. Mater. 9/2026)

Key Points

The sodium-potassium alloy coats and fills pores in porous carbon, improving interaction.
Key evidence indicates a spontaneous coating of the carbon structure after contact with the alloy.
Analysis of wetting interactions provides insights into electrochemical performance for battery systems.
Highlights need for further exploration of these interactions to optimize battery designs.
