Anion-Cation Targeted Regulation Enables Ultrafast and Stable Sodium Metal Batteries at Low Temperatures.
Anion-dominated solvation and artificial interfacial engineering have been intensively pursued for low-temperature sodium-metal batteries (SMBs), yet they face constraints from temperature-sensitive solvation dynamics and interfacial control. Here we propose anion-cation-targeted regulation via Sn(OTf)2 that simultaneo...
