A High-capacity Dual Core-shell Structured MWCNTs@S@PPy Nanocomposite Anode for Advanced Aqueous Rechargeable Lithium Battery

Abstract

Anode material with high capacity for aqueous rechargeale lithium batteries (ARLBs) is very rarely reported. Here we found that our prepared dual core–shell structured MWCNTs@S@PPy nanocomposite shows excellent electrochemical performance. Its initial discharge capacity in saturated LiAc aqueous electrolyte is very high, which is up to 481 mAh g-1 based on the weight of the composite and 879 mAh g-1 based on the sulfur content. It shows excellent rate capability. When nanotube LiMn2O4 is used as a cathode, the assembled ARLB can deliver an energy density of 110 Wh kg-1 based on two electrodes and excellent cycling. These results show the great promise for the practical application of ARLBs once again.
