Lithium‐sulfur (Li‐S) batteries are of considerable research interest for their application potentials in high‐density energy storage. However, the practical application of Li‐S batteries is severely plagued by polysulfide (PS) dissolution and serious safety concerns caused by flammable sulfur and p...
