4,4 -Hydrazobis(1-methylpyridinium) as a Two-Electron Posolyte Molecule for Aqueous Organic Redox Flow Batteries

Author(s): Lebel H; Rochefort D; Lai C; Boulanger T; Debiais A; Hamlet L; Maleki M; Goulet MA;

Aqueous organic redox flow batteries (AORFBs) are a safe and sustainable solution for the storage of intermittent renewable energy. While several highly soluble two-electron organic molecule negolytes have been developed for AORFBs, most reported organic posolyte species exchange only one electron. Herein, readily available 4,4'-hydrazobis(1-methylpyr ...

High selectivity framework polymer membranes chemically tuned towards fast anion conduction

Author(s): Fang J; Zhang G; Goulet MA; Zuo P; Zhou Y; Li H; Jiang J; Guiver MD; Yang Z; Xu T;

Studying ion transport in the interaction confinement regime has important implications for membrane design and advanced electrochemical devices. A key example is the rapid-charging capability of aqueous organic redox flow batteries, enabled by near-frictionless Na+/K+ transport within triazine framework membranes. However, achieving similar breakthroughs ...

In situ electrochemical recomposition of decomposed redox-active species in aqueous organic flow batteries

Author(s): Jing Y; Zhao EW; Goulet MA; Bahari M; Fell EM; Jin S; Davoodi A; Jónsson E; Wu M; Grey CP; Gordon RG; Aziz MJ;

Aqueous organic redox flow batteries offer a safe and potentially inexpensive solution to the problem of storing massive amounts of electricity produced from intermittent renewables. However, molecular decomposition represents a major barrier to commercialization-and although structural modificat ...
