Conflicting entropy-driven zwitterionic dry polymer electrolytes for scalable high-energy all-solid-state batteries.

ABSTRACT: Inorganic electrolytes dominate all-solid-state batteries (ASSBs), but face critical limitations, including interfacial instability, complex manufacturing, and challenges in operating under commercially viable conditions. Here, we present a transformative approach using zwitterionic dry polymer electrolytes (ZPEs) designed via a conflicting entropy strategy to enable scalable energy-dense ASSBs. Guided by Flory-Huggins theory, liquid-state zwitterionic monomers exhibit higher mixing entropy with Li salts compared to conventional long-chain polymers, forming homogeneous monomer/salt mixtures with enhanced intermolecular electrostatic interactions to promote salt dissociation. In situ polymerization of these mixtures yields directionally aligned ion channels decoupled from the polymer backbo
