Single-Ion-Conducting Polymer Electrolytes for Rechargeable Alkaline Ag-Zn Batteries.

ABSTRACT: Recently, we reported on the synthesis and performance of a cross-linked single-anion-conducting solid-state electrolyte (SSE) based on quaternized poly(dimethylaminomethylstyrene) (pDMAMS⁺) via initiated chemical vapor deposition (iCVD). In the homopolymer pDMAMS⁺-based SSE, the cross-linking occurs at the positively charged ammonium cation sites, hindering ion transport and conductivity. To improve ionic conductivity, we now report on a copolymer system, comprising DMAMS and divinylbenzene (DVB). Incorporating DVB moves the cross-links to the polymer backbone leaving the quaternary ammonium cation and its paired anion with maximal dynamic freedom. We evaluate the structure-transport relationships of a series of p[DVB-DMAMS] copolymers with varying DVB content using
