Trace Anion‐Receptor Chemistry for Stable Carbonate Electrolytes Toward Long‐Life Sodium Metal Batteries
Sodium metal batteries (SMBs) offer a promising route toward cost‐effective energy storage, but their operation in carbonate electrolytes is limited by coupled NaPF6 degradation and interfacial instability. Trace moisture triggers salt hydrolysis and HF formation, continuously disrupting SEI/CEI chemistry and aggravati...
