ABSTRACT Alkali metal (Li, Na, and K) batteries (AMBs) have attracted widespread attention in recent years because of their high theoretical specific capacity and attractive energy density. However, they still suffer from uncontrollable dendrite growth and sluggish conductivity during cycling, which lead to security issues and inferior cycling ...

ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.
