A facile synthetic strategy for highly microporous Schiff-base polymer as sulfur hosts for lithium-sulfur batteries

SO3-COF@Al2O3 modified cathode electrode materials enhance the cycling ability of lithium sulfur batteries

“…However, the development and application of LSBs still face many problems, such as the insulation properties of elemental sulfur and Li 2 S, the shuttle effect caused by the solubility of the intermediate polysulfides (LiPSs) in the electrolytes, and the volume expansion of the cathode electrode materials during cycling. [5][6][7] In particular, the ''shuttle effect'' greatly limits the actual specific capacity, cycle life, and magnification performance of LSBs. In response to the above issues, researchers have carried out a lot of research on composite modification of cathode electrodes, surface modification of lithium metal cathode electrodes and the development of new anode electrodes and new electrolytes.…”
