S-based redox materials are promising next-generation energy storage solutions Identifying electrode and electrolyte properties that facilitate polysulfide reduction reactions is critical for rational material designs for S-based batteries. The authors reveal that the effectiveness of the polysulfide reduction is governed by the resolved binding strength of polysulfide on the electrode surface, which is dictated by the competition between electrode’s polysulfide chemisorption strength and solvent’s polysulfide solvation strength. Using Ti-based model compounds (TiX) as examples, the polysulfide reduction kinetics and S use increase with increasing polysulfide chemisorption strength of TiX, which can be associated with the decreasing electronegativity of nonmetal element (X). Strong coordinating solvent reduces catalyst’s efficacy by reducing the binding strength between polysulfide and the catalysts, highlighting that a weak solvent coordination is a critical selection criterion for effective catalysis in Li-S batteries. The study reveals phys. origins controlling the catalytic processes of polysulfide reduction reactions and unravels the interplay of solvent-polysulfide-catalyst competition for achieving higher-energy and reversible S-based energy storage.
