Role of Polysulfides in Self-Healing Lithium–Sulfur Batteries

To overcome the cycling instability and inefficiency that are inherent to lithium–sulfur batteries, a conceptually new approach is adopted based on mitigating the sulfur loss by creating a dynamic equilibrium between the dissolution and precipitation of lithium polysulfides at the electrode interface. Novel lithium polysulfide electrolytes that play a major role in self-healing lithium–sulfur batteries are developed.
