        "abstract": "The practical realization of organic redox flow batteries (RFBs) for grid-scale energy storage is limited by complex active material degradation pathways frequently featuring one or more free radical species. Here we develop strategies for stabilization of mono- and di-radicals in organic 2e- electrolytes. Leveraging steric differences between isomers of cyclic triindole catholytes, we show that capacity fade arising from radical-based processes can be controlled by adjusting the chirality, intramolecular chiral induction, and degree of out of plane torsion \u2013 all without influencing redox potential. We further show that diradical decomposition follows at least two pathways, the preference for which can be biased using chirality, suggesting the presence of a chirality induced spin selectivity (CISS) effect. Once stabilized, triindole radicals can be co-formulated directly with viologen based electrolytes in 2e- symmetric, membraneless and all-organic full-cell configurations with little fade, air-tolerance, > 75% energy efficiency, robust self-discharge resistance and plausible pathways for large scale production.",
