Description |
Although lithium-sulfur batteries possess five-fold higher theoretical capacity than the state-of-the-art
lithium-ion batteries, the migration of polysulfide between the electrodes remains as a problem area.
In order to overcome this issue, numerous strategies have been adopted. Herein, we introduce a novel
1,3,5 benzene tricarboxylate-manganese (Mn-BTC) metal organic framework (MOF) coated-Celgard
(2320) separator which acts as permselective in a Li-S cell. The Li-S cell with coated membrane
exhibited higher discharge capacity than the uncoated one. The diffusion of polysulfides is successfully
blocked by the separator due to the repulsive ionic forces provided by the COOe that is present in the
periphery of Mn-BTC MOF which was confirmed by XPS and XRD analyses
