Abstract:
In emerging lithium-sulfur (Li-S) batteries, the significant redox kinetic barriers and the severe shuttle effect of lithium polysulfides (LiPSs) are major challenges that hinder their practical use. In this study, Co/Cu heterostructure nanoparticles, highly dispersed within N-doped hollow carbon spheres (Cu/Co@NC), are meticulously designed and synthesized, serving as both an adsorbent and a catalyst for advanced Li-S batteries.
