Abstract
Abstract High redox kinetic barriers and the severe shuttle effect of lithium polysulfides (LiPSs) are two primary challenges for the practical deployment of lithium‐sulfur (Li–S) batteries. Herein, highly dispersed Co nanoparticles embedded into S, N co‐doped hollow chained carbon sphere (Co@SNC) are well‐designed and prepared and served as an effective host catalyst for Li–S batteries. Doped S‐atoms can effectively modulate the electronic metal‐support interaction between Co nanoparticles and carbon matrix, which induces charge redistribution and increased d‐orbital energy levels. Co@SNC can provide strong chemical interaction with LiPSs and reduce the Li + diffusion barrier, which can effectively anchor…
