Oligoanilines as a suppressor of polysulfide shuttling in lithium–sulfur batteries

Materials Horizons, 2017
Amine-capped aniline trimer (ACAT) with a strong interaction with polysulfides (LiPS) facilitates the formation of bulky ACAT–LiPS complexes, which are then size-selectively sieved and stabilized within the cathode in lithium–sulfur batteries.

A New Graphitic Nitride and Reduced Graphene Oxide-Based Sulfur Cathode for High-Capacity Lithium-Sulfur Cells

Energies, 2022
Lithium-sulfur (Li-S) batteries can provide at least three times higher energy density than lithium-ion (Li-Ion) batteries. However, Li-S batteries suffer from a phenomenon called the polysulfide shuttle (PSS) that prevents the commercialization of these
