英文摘要	Bismuth sulfide nanorod array is directly grown on nickel foam (R-Bi2S3/NF) to serve as a completely carbon and binder-free 3D porous oxygen electrode material for lithium-oxygen (Li-O-2) batteries. The synergistic effect of the fast kinetics of electron transport and gas and electrolyte diffusion provided by the continuous free-standing network structure and the excellent electrocatalytic activity of the bismuth sulfide nanorod array enables outstanding performance of the oxygen electrode. Li-O-2 battery with the free-standing R-Bi2S3/NF oxygen electrode exhibits high energy efficiency (78.7%), good rate capability (4464 mA h g(-1) at 1500 mA g(-1)), as well as excellent cyclability (146 cycles) while maintaining a moderate specific capacity of 1000 mA h g(-1). The effect of cathodes with different reactant (O-2) and intermediate (LiO2) adsorbability on the product (Li2O2) growth model is studied by first-principle calculations. The strong O-2 adsorption and weak LiO2 adsorption on Bi2S3 drives the growth of large-size Li2O2 particles via solution growth model. Remarkably, the large-area pouch-type Li-O-2 battery delivers an energy density of 330 Wh kg(-1). The present results open up a promising avenue toward developing novel electrode architecture for high-performance Li-O-2 batteries through controlling morphology and functionality of porous electrodes.
