摘要：

Anode materials with high capacity for aqueous rechargeable lithium batteries (ARLBs) are very rarely reported. Here we found that a dual core-shell structured MWCNTs@S@PPy nanocomposite prepared by us shows excellent electrochemical performance. Its initial discharge capacity in a saturated LiAc aqueous electrolyte is very high, which is up to 481 mA h g-1based on the weight of the composite and 879 mA h g-1based on the sulfur content. It shows excellent rate capability. When nanotube LiMn2O4is used as a cathode, the assembled ARLB can deliver an energy density of 110 Wh kg-1based on two elec...
