MoS2 coated separator as an efficient barrier for inhibiting shuttle effect of polysulfide

Attenuating the Polysulfide Shuttle Mechanism by Separator Coating

“…This is also in agreement with various references in the literature where molybdenum sulfide is used as a host material in cathodes and also in interlayers. [19,30,31,46]…”

“…Various publications on this topic can already be found in literature, in which graphene or other porous carbon‐based intermediate layers were additionally introduced into the cell design [26,28] . Composite materials made of carbon and transition metal compounds also showed good results [27,29,30,31] . However, coated separators also lend themselves to keeping cell fabrication as simple as possible.…”

“…[26,28] Composite materials made of carbon and transition metal compounds also showed good results. [27,29,30,31] However, coated separators also lend themselves to keeping cell fabrication as simple as possible. For example, Abbas et al studied polypropylene separators with a slurry-based coating.…”

Recent advances in modified commercial separators for lithium–sulfur batteries

“…12b), the metal sulfides have a high affinity for LiPSs, indicated by their highly negative adsorption energies. Liu et al 308 used MoS 2 nanosheets, which are known to have excellent Li conductivity, to coat a standard PP separator. An LSB with the modified separator exhibited a 51% higher initial capacitance at a low current density of 0.1C and maintained a high 752 mA h g −1 capacity at 2C.…”

Sucrose derived microporous–mesoporous carbon for advanced lithium–sulfur batteries

“…Recently, metal oxides [4], metal sulfides [5], carbon nanotube [6], and porous carbon [7] have been developed as sulfur host materials. Among these materials, porous carbon can capture highly dispersive sulfur particulates, improve the conductivity and alleviate the volume effect [8][9].…”
