Abstract
HighlightsA bi-service host with lithiophilic/sulfiphilic Fe2CoSe4 quantum dots embedded in three-dimensional ordered nitrogen-doped carbon skeleton is elaborately developed for both the sulfur cathode and Li anode synchronously.The highly dispersed Fe2CoSe4 quantum dots can not only act as a redox accelerator to promote the bidirectional conversion of LiPSs but also regulate the uniform Li plating/stripping to mitigate the growth of Li dendrite.The assembled Li-S full batteries achieve excellent long-term cyclability and a remarkable areal capacity of 8.41 mAh cm2 at high sulfur loading of 8.50 mg cm2, and the pouch full battery also displays high capacity and cycling-stability at lean electrolyte condition.
