A new lithium polysulfide (PS) trapping strategy based on electrostatic attraction between imidazolium groups and PSs has been demonstrated. Simple introduction of main-chain imidazolium-based ionic polymers into sulfur cathodes results in effective suppression of the PS shuttle effect, thus significantly improving cycling stability of lithium–sulfur batteries.
