Summary: Sulfonated polymers are widely used in fuel cells as proton-conducting materials and their ionic transport features make them attractive for electrolytes in lithium-ion/metal batteries. This study demonstrates the use of swollen nanofibrous Nafion as effective Li+-conducting channels, which enhances Li+ transport by forming a porous ionic matrix and promoting partial desolvation of Li+-solvates. The application of this membrane in Li-symmetric cells and Li-metal full cells shows excellent cycling performance and stabilized Li-metal anode, providing a strategy to convert sulfonated polymers into efficient Li+ electrolytes and promoting the development of high-energy-density LMBs.

Summary: This study evaluated the separation ability of biased cyclical electrical field-flow fractionation (BCyElFFF) for polyvinyl pyrrolidone-coated and poly(ethylene glycol)-coated silver nanoparticles (AgNPs) with different electrophoretic mobilities, and elucidated the mechanism behind the formation of NOM corona on these AgNP surfaces. Furthermore, it was observed that the survival rates of E. coli exposed to AgNPs with or without NOM corona collected during repeated BCyElFFF runs increased with increasing NOM concentration, indicating the negative effect of NOM coronas on the bioavailability of AgNPs. These findings highlight the powerful capability of BCyElFFF in studying the fate and transformation of nanoparticles in aqueous environments.
