Interfacial Electric Field Modulation of 1D/2D FeCo2O4/g-C3N4 Heterostructures for Lithium Sulfur Batteries Over Wide Temperatures

Abstract

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