Key Points

The study aims to address interfacial instability in zinc metal anodes, focusing on improving their long-term durability.
Utilization of sulfonated polybetaine for nanomicelle self-assembly.
Evaluation of interfacial chemistry changes after treatment.
Comparison of zinc anode performance with and without zwitterionic surfactants.
Significant reduction in dendrite growth observed in treated zinc anodes.
Enhanced resistance to parasitic side reactions noted.
Improved cycling stability demonstrated over extended periods.

Abstract

The long-term durability of Zn metal anodes is severely compromised by interfacial instability, primarily stemming from uncontrolled dendrite growth and parasitic side reactions. Herein, sulfonated polybetaine (SPE), a zwitterionic surfactant...
