Slide-Crosslinked Polyrotaxane Topological Networks: Quasi-Solid Electrolyte for High-Voltage Lithium Metal Batteries.

ABSTRACT: Although polymer-based electrolytes offer advantages like low cost, favorable interfacial compatibility, and processability for solid-state lithium metal batteries with high safety and high energy density, conventional linear polymer-based electrolytes suffer from inadequate oxidation resistance and mechanical strength at operating voltages above 4.5 V, causing rapid capacity degradation and reduced battery lifespan. Inspired by the mechanical slide-ring structure of polyrotaxanes (PR), a series of high-voltage-resistant sliding crosslinked quasi-solid electrolytes (PMBA-PPR_x) is designed and synthesized via in situ thermal polymerization of varying amounts of vinyl functional polyrotaxanes (PPRs) with N,N'-methylenebisacrylamide (MBA). The optimal PMBA-PPR₅ electroly
