| 英文摘要 | An exceptionally strong solvation effect of dimethyl sulfoxide (DMSO) on I-2 is identified by the largest shift observed so far of the I-2 Raman peak with respect to I-2 vapor and by elongated I-I bond lengths in first-principles molecular-dynamics simulations. This effect together with strong binding by an RuO2 surface to I-2 is found to invert the direction of the reaction I-+I2I3- to the left-hand side. Inspired by this finding, we prepared a Li-O-2 battery with the Li/DMSO+LiI/RuO2 structure. The synergic action of DMSO and RuO2 on I-2 is found to suppress the shuttle effect of the redox mediator (RM) by anchoring I-2 molecules, the oxidation product of the RM. Significantly enhanced stability is demonstrated over 100 cycles at charging voltage below 3.65 V. |
