| Outline of Final Research Achievements |
In the development of lithium (Li)-oxygen (O2) rechargeable battery, improvement of the rechargeability is one of the key issues to be solved. Here, a novel strategy to solve these issues is explored, in which polymer-wrapped single-walled carbon nanotubes (SWNTs) are used for a cathode material. Poly[2,2’-(2,6-pyridine)-5,5’-bibenzimidazole] (PyPBI) employed as the wrapping polymer of SWNTs serves to coordinate Li ion to facilitate the favorable deposition of the discharge products on SWNTs during discharge reaction in the cell cathode. As a result, rechargeability of the cell (SWNT/PyPBI-cell) is improved compared to the cell having non-wrapped SWNTs as the cathode (SWNT-cell).
