Summary: This study designs a porous carbon-based sulfur electrode for high-energy Li-S batteries. By impregnating the porous carbon with a high concentration of sulfur and reducing the content of conductive agent and binder, crack formation during electrode drying can be inhibited. Two distinct electrically conducting networks are utilized to reduce battery polarization and achieve a capacity of 690 mAh g(-1) even after 100 cycles. Pouch cells are prepared to evaluate the practical performance, resulting in a capacity of 741 mAh and a cathode energy density of 1001 Wh kg(-1). These findings are expected to guide the further development of high-energy-density cathode materials for Li-S batteries.
