Abstract
In recent years, increasing performance requirements for fuel cells, water electrolyzers, and secondary batteries have driven the development of polymer electrolytes capable of selective and efficient ion transport. In particular, ion transport within polymer electrolytes is governed not only by membrane hydrophilicity and the properties of charged groups but also by the polymer network structure, including mesh size and polymer-ion interactions. Therefore, precise molecular-level structural control is essential for the rational design of high-performance polymer electrolytes.
In this study, anion-conductive network gel polymer electrolytes with quaternary ammonium crosslinking sites were fabricated to investigate the effects of network structures on ion transport properties and to establish molecular design guidelines for polymer electrolytes for battery applications. The network gel electrolytes were prepared through simultaneous network formation and quaternization using multifunctional amine crosslinkers. Specifically, four crosslinking agents, including two alkyl diamines with different chain lengths, one aromatic diamine, and one aromatic triamine, were employed to construct different network structures. The relationships among the resulting network structures, local electrostatic environments, ion transport properties, and the charge-discharge performance of rechargeable zinc-air batteries were investigated.
