Accelerated Conversion of Polysulfides for Ultra Long‐Cycle of Li‐S Battery at High‐Rate over Cooperative Cathode Electrocatalyst of Ni_0.261Co_0.739S₂/N‐Doped CNTs (Adv. Sci. 32/2024)

Cooperative Cathode Electrocatalyst In article number 2402389, Min Ho Seo, Won Bae Kim, and co-workers report multifunctional electrocatalyst cathode of NixCo1-xS2 nanocrystals dispersed on nitrogen-doped porous CNTs for Li-S batteries. The carbon backbone provides buffer-space and chemical active-sites, and the NixCo1-xS2 can effectively catalyze polysulfides, thereby inducing weaker sulfur bond strength for sustainable cooperative catalysis by facilitating covalent-site-dependent mechanism in NiOh2+–S–CoOh2+ bonding states.
