Dual Role of Mo6S8 in Polysulfide Conversion and Shuttle for Mg–S Batteries [PDF]

open access: yesAdvanced Science, 2022
AbstractMagnesium–Sulfur batteries are one of most appealing options among the post‐lithium battery systems due to its potentially high energy density, safe and sustainable electrode materials. The major practical challenges are originated from the soluble magnesium polysulfide intermediates and their shuttling between the electrodes, which cause high ...

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

open access: yesMaterials 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.
