Abstract
Lithium metal batteries are promising energy-storage systems with high energy density; however, their development remains limited by the insufficient ionic conductivity, low lithium-ion transference number, and unstable electrode interfaces of polymer electrolytes. Zwitterionic polymers contain covalently linked cationic and anionic groups and can promote lithium-salt dissociation, restrict anion migration, and regulate interfacial ion distribution through strong dipolar and coordination interactions.
This presentation first introduces the molecular structures and synthetic strategies of zwitterionic polymers and discusses their structure–ion transport relationships. Zwitterion-based solid, gel, and composite polymer electrolytes for lithium metal batteries are then systematically reviewed. A zwitterionic–single-ion conducting nanofiber composite electrolyte is subsequently presented, in which the continuous nanofibrous framework and immobilized anionic groups improve selective Li⁺ transport and membrane stability. Finally, coordination-driven zwitterionic core–shell polymers are discussed as functional nanostructured transport units. Controlled polymerization, self-assembly, and selective crosslinking are employed to construct continuous and low-tortuosity ion-conduction pathways. By integrating molecular coordination, nanostructural engineering, and interfacial regulation, this presentation highlights the development of zwitterionic polymer electrolytes from lithium-salt dissociation toward directional Li⁺ transport.
Keywords: zwitterionic polymers, lithium metal batteries, solid polymer electrolytes, single-ion conductors, directional ion transport
