Abstract
En 中文
Li-CO2 batteries have attracted increasing attention due to their high energy density and CO2 capture potential. However, the sluggish reaction kinetics of the CO2 reduction reaction (CO2RR) and evolution reaction (CO2ER) at the cathode lead to large overpotential and poor cycle stability. Herein, N-doped carbon nanotubes (NCNTs)supported layered double hydroxides (LDHs) derived CoFe alloy nanoparticles were synthesized as the cathode catalyst for Li-CO2 batteries. The framework of LDH-derived CoFe alloy nanoparticles supported on NCNTs provides high-density active sites and excellent electrical conductivity for battery reactions. The assembled battery demonstrates a notably high discharge capacity of 18,599 mAh g- 1, a relatively low overpotential of 1.59 V, and exceptional cycling performance, maintaining stable operation for 112 cycles with a limited capacity of 500 mAh g- 1.
