Energy storage by means of lithium-sulfur batteries holds great promise. They are inexpensive and have a high potential energy density. Unfortunately, the battery's cycling performance is greatly diminished by the shuttle effect of polysulfide. Metal-organic frameworks (MOFs) with high specific surface area, nanopore size, and plentiful porosity have been proven to help prevent polysulfide migration in recent years. In this research, partially nitro-functionalized MIL-101(Fe) has been produced by combining different proportion ligands. As an electron-withdrawing group, the nitro group can reduce the charge density of the metal sites and improve the adsorption capacity of the material to polysulfides. MIL-101-NO2-0.25 showed the performance with an initial discharge capacity of 1051.5 mAh g-1 at a current density of 0.5 C and maintained at 908 mAh g-1 after 250 cycles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
