In situ-formed cobalt nanoparticles embedded nitrogen-doped hierarchical porous carbon as sulfur host for high-performance Li-S batteries

Low redox kinetics and shuttle effect of polysulfides (PSs) is a grand challenge for practical applications of lithium-sulfur (Li-S) batteries. Herein, cobalt (Co) nanoparticles embedded inside nitrogen (N)-doped hierarchical porous carbon (MgCo-HC) are prepared via one-pot approach. As a result, Mg...
