Abstract

Lithium sulfide (Li ₂ S)-based rechargeable battery has aroused much interest in the last few years because of its enhanced safety stemming from eliminating lithium metal anode and its high energy density. Here, we demonstrated a new-designed Li ₂ S-based full cell with high energy density composed of the free-standing Li ₂ S-rGO cathode and MnO ₂ -rGO anode. Li ₂ S-rGO cathode and rGO-MnO ₂ anode exhibit a high capacity even based on the whole electrode, 367.5 mAh g ⁻¹ _{Li2S electrode} and 644.1 mAh g ⁻¹ _{MnO2 electrode} , respectively, which are benefitted from their free-standing nature and unique morphology of active material wrapped by rGO sheets. When incorporating Li ₂ S-rGO cathode and MnO ₂ -rGO anode, Li ₂ S/MnO ₂ full cell can achieve a high capacity of 587.5 mAh g ⁻¹ _Li2S and a high energy density of 827.3 Wh kg ⁻¹ _Li2S at 0.2 C.
