Characterization Of Zwitterion/Salt Electrolyte Blends For Organic Solid Electrolytes In Lithium-Ion Batteries, Sage Alling, Will Vasser Oct 2025

Characterization Of Zwitterion/Salt Electrolyte Blends For Organic Solid Electrolytes In Lithium-Ion Batteries, Sage Alling, Will Vasser

College of Engineering Summer Undergraduate Research Program

Progress toward durable and energy-dense lithium-ion batteries has been hindered by instabilities at electrolyte–electrode interfaces, leading to poor cycling stability, and by safety concerns associated with energy-dense lithium metal anodes. Organic Solid electrolytes (OSEs) can help mitigate these issues; however, OSE conductivity is often limited by sluggish dynamics through rubbery domains. Recent work has suggested that zwitterionic OSEs can self-assemble into superionically conductive domains, permitting decoupling of ion motion and liquid rearrangement timesscales. Although crystalline domains are conventionally detrimental to ion conduction in SPEs, we this work suggests that properly designed semicrystalline OSEs with labile ion–ion interactions and tailored ion …
