| 제목 | N-doped graphene nanosheets as an electrode for lithium rechargeable cells and their electrochemical properties |
| 초록 | In this present work, we introduced a thermal exfoliation of conducting polymer (poly (diallyldimethylammonium chloride), PDDA) coated graphene oxide electrode for rechargeable lithium-sulfur battery and demonstrate that nitrogen doped thermal exfoliation graphene sheets (NTEGS) can effectively induce chemical adsorption of sulfur on the surface carbon framework and serves as a good electron conductive framework. The electrochemical performances of NTEGS/Sand GS/S composites were investigated by using cycle voltammetry test measurement. Our investigation is that the NTEGS/S cathodes show excellent coulombic efficiency (＞95%), cycling stability (60% retention within 100 cycle), and a good capacity of around 650 mAh g-1 after 100 cycle. |
