Isolated Co single atoms in nitrogen-doped graphene for aluminum-sulfur batteries with enhanced kinetic response
文献摘要：
Al-S batteries are promising next generation energy storage devices due to their high theoretical energy density(1340 Wh kg-1),low cost,and safe operation.However,the electrochemical performance of Al-S batteries suffers poor reversibility owing to slow kinetic processes determined by the difficulty of rever-sible conversion between Al and S.Here,we proposed a single-atom catalysts comprising Co atoms embedded in a nitrogen-doped graphene(CoNG)as an electrochemical catalyst in the sulfur cathode that renders a reduced discharge-charge voltage hysteresis and improved sulfur utilization in the cathode.The structural and electrochemical analyses suggest that the CoNG facilitated both the formation and oxida-tion of AlSx during the electrochemical reactions of the sulfur species.Consequently,the CoNG-S compos-ite can deliver a considerably reduced voltage hysteresis of 0.76 V and a reversible specific capacity of 1631 mAhg-1 at 0.2 Ag-1 with a sulfur utilization of more than 97％.
