Article Synopsis
- Pyridinium electrolytes are being investigated for their potential in flow batteries, focusing on their charge-discharge processes and cycling stability, which are not well understood.
- The study uses a synthetic library of bispyridinium compounds to analyze their performance at various potentials and identifies a crucial energy gap metric that predicts capacity fade mechanisms.
- Advanced spectroscopy techniques reveal two different energy gap regimes in their electrochemical performance, linking capacity fade to free radical formation and showing that π-dimerization helps minimize negative reactions with impurities like oxygen, allowing for better use in air-exposed systems.
Article Synopsis
- A new synthetic approach is introduced that diversifies polymer structures to create specific free volume elements (FVEs) designed to serve as solvation cages for lithium, enhancing membrane performance.
- The resulting membranes demonstrate improved ionic conductivity and ion transport efficiency, making them potential candidates for stabilizing anodes in high-voltage lithium metal batteries.
