Covalently introducing sulfur in a thiol-rich MOF toward advanced
The shuttle effect and sluggish reaction kinetics have hindered the practical application of lithium-sulfur (Li-S) batteries. In this work, a thiol-rich MOF was in situ synthesized on carbon nanotube (CNT) and sulfur was covalently connected to this composite to form a MOF-sulfur copolymer (S-UiO-66(SH) 2 @CNT). Benefiting from …Web
