Prelithiation of Nanostructured Sulfur Cathode by an "On-Sheet" Solid-State Reaction.
A novel "on-sheet" solid-state chemical reaction method is designed to fabricate a nanostructured Li2S-reduced graphene oxide (rGO) cathode using a semi-sacrificial sulfur-graphene oxide template. The as-fabricated Li2S-rGO nanocomposite shows a superior electrochemical performance, e.g., high utilization of Li2S active materials (86.3 wt%), long cell life (1000 cycles), and excellent rate ability.
