| 英文摘要 | The unsatisfactory stabilities of carbon-based cathodes and lithium anodes are the major hurdles limiting the development of Li-air (O-2) batteries. Herein, we propose an extremely simple cell formation process for nonaqueous Li-O-2 batteries, by a discharge-charge process in argon prior to O-2 atmosphere, to produce protective films on both CNTs-cathode and lithium-anode surfaces. The films are mainly composed of lithium fluoride derived from LiTFSI decomposition and endows lithium oxygen batteries with enhanced cycling stability (>200 cycles) under a consistent capacity condition (1000 mAh g(-1)). This study reveals that LiF-rich films could effectually suppress the parasitic reactions of electrodes against the reactive intermediates and electrolyte attacks. This simple approach provides a new strategy to protect both electrodes for lithium oxygen batteries. |
