Regulating ion transport and solvation chemistry in zwitterionic gel polymer electrolyte for high-performance quasi-solid-state batteries

Proceedings of the National Academy of Sciences, Volume 123, Issue 3, January 2026. <br/>SignificanceGel polymer electrolytes (GPEs) are promising candidates for next-generation lithium metal batteries. However, the reverse migration of free anions and strong ion–solvent interactions result in uneven Li deposition and sluggish interfacial Li+…
