Abstract

In the development of lithium (Li)–oxygen (O₂) rechargeable batteries, the improvement of the rechargeability is one of the key issues to be solved. Herein, a novel strategy to solve this issue is explored using polymer-wrapped single-walled carbon nanotubes (SWCNTs) as the cathode material. Poly[2,2’-(2,6-pyridine)-5,5’-bibenzimidazole] (PyPBI), employed as the wrapping polymer of the SWCNTs, served to coordinate Li ions and to facilitate a favorable deposition of the discharge products on the SWCNTs during the discharge reaction at the cell cathode. As a result, the rechargeability of the cell (SWCNT/PyPBI-cell) was improved compared to the cell having nonwrapped SWCNTs as the cathode (SWCNT-cell).
