Abstract High-energy lithium-sulfur (Li-S) pouch cell are limited by the insufficient capacities and stabilities of their cathodes under practical electrolyte/sulfur (E/S), electrolyte/capacity (E/C), and negative/positive (N/P) ratios. Herein, we fabricated an advanced cathode comprising highly active Fe single atom catalysts (SACs) and porous carbon to attain 361.8 W h kg−1 Li-S pouch cells satisfying low E/S (2.0), E/C (1.9), and N/P (2.3) ratios with high sulfur loadings (8.4 mg cm−2). We designed high-activity Fe SACs by manipulating their local environments using electron exchangeable binding (EEB) sites. Introducing EEB sites composed of two different types of S species, namely, thiophene-like-S and oxidized-S, adjacent to Fe SACs, promoted the kinetics of the Li2S redox reaction by providing additional binding sites and modulating the Fe d-orbital levels via electron exchange with Fe. This desirable cathode electrocatalysis is maximized by the intimate contact of Fe SACs with the S species, confined together into porous carbon.
