The remarkable theoretical specific capacity of elemental sulfur (≃ 1675 mA h/g), its eco-friendly nature, and its abundance make lithium-sulfur (Li-S) batteries an attractive alternative to current lithium-ion batteries. Nevertheless, their cycle life has so far been limited due to certain drawbacks. A notable challenge is the formation of long-chain, soluble lithium polysulfides during the discharge and their shuttling through the conventional electrolytes, which leads to a depletion of the active material and formation of an insulating layer around the anode. All these processes result in an irreversible capacity fade in Li-S batteries. To tackle these issues, numerous studies have focused on structural optimization of sulfur cathodes including utilization of sulfur/carbon copolymers. In order to synthesize S/C copolymers, many researchers have employed the inverse vulcanization reaction as a facile synthesis method which provides a straightforward way for controlling sulfur content.
