Abstract

This work reports a FeCo2O4/g-C3N4 heterostructure with a built-in electric field as a separator modifier to synergistically adsorb and catalyze the electrochemical conversion of lithium polysulfides, enabling a low decay rate of 0.058% over 1000 cycles and a high areal capacity of 6.2 mAh cm−2 over a wide temperature range (0 to 60 °C).
