S-S bonds in organodisulfides can break and obtain Li+ and e- in the discharge of lithium batteries. Organodisulfides provide precise lithiation sites, and therefore are valuable models for the study of redox reactions in lithium batteries. To understand their electrochem. behavior, we investigate three disulfides with different N-containing heterocycles including 2,2′-dipyridyl disulfide (2,2′-DpyDS), 4,4′-dipyridyl disulfide (4,4′-DpyDS), and 2,2′-dipyridyl disulfide-N,N’-dioxide (DpyDSDO). The three disulfides all show higher discharge voltage plateaus due to the electron-withdrawing groups: DPDS (2.20 V) < 2,2'-DpyDS (2.45 V) = 4,4'-DpyDS (2.45 V) < DpyDSDO (2.80 V). In particular, 2,2'-DpyDS exhibits an outstanding 69% capacity retention over 500 cycles. Our theor. simulations show that lithium pyridine-2-thiolate, the discharge product of 2,2'-DpyDS, forms compact clusters via N···Li···S bridges coordinated by lithium ions, which can help reduce its dissolution in liquid electrolyte, and therefore increase the cycle life. Liquid chromatog.-mass spectrometry is demonstrated to be a powerful tool for the investigation of discharge/recharge products of soluble organodisulfides in rechargeable lithium batteries. In some applications, this compound(4556-23-4)SDS of cas: 4556-23-4 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
