Promoting Electrochemical Reactions with Dual-Atom Catalysts for High-Rate Lithium-Sulfur Batteries.

ABSTRACT: Sulfur cathodes offer a promising solution for high-energy-density, cost-effective, and sustainable energy storage. However, their practical application is limited by sluggish and complex multistep sulfur redox reactions (SRRs), involving both electrochemical and chemical processes. Herein, it is demonstrated that accelerating electrochemical processes, particularly Li₂S nucleation, over competing chemical pathways is fundamental to minimizing sulfur loss and achieving high-rate performance. To this end, a scalable and cost-effective strategy is presented for synthesizing a series of 3d transition metal-bismuth (TM-Bi) atomic pairs anchored on carbon nitride (CN) and investigate their potential to activate SRRs in lithium-sulfur batteries (LSBs). An initial screening identifies
