Ph disulfide (PDS) is employed as an electrolyte additive in lithium-carbon dioxide (Li-CO2) batteries to allow for a solution-mediated carbon dioxide reduction pathway. Thiophenolate anions, generated via electrochem. reduction of PDS, act as CO2 capture agents by forming the adduct S-Ph carbonothioate (SPC-) in solution A mechanism of SPC–mediated CO2 capture and utilization is proposed and supported via carbon-13 NMR spectroscopy and Fourier-transform IR spectroscopy. Reversible formation and decomposition of lithium carbonate and amorphous carbon during cycling, facilitated by the solution-mediated pathway, are demonstrated with an array of characterization techniques. Li-CO2 batteries employing the PDS additive show vastly improved capacity, energy efficiency, and cycle life. The enhanced Li-CO2 battery performance offered by the proposed solution-mediated reaction pathway offers a compelling step forward in the pursuit of reversible CO2 utilization.1,2-Diphenyldisulfane(cas: 882-33-7Reference of 1,2-Diphenyldisulfane) was used in this study.
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Reference of 1,2-Diphenyldisulfane
