Control of fluorine nature on single layer graphene for future energy applications

초록

Fluorinated graphene has been utilized by energy applications such as the cathode in lithium primary batteries and supercapacitors because of its unique properties that are high energy density, high average operating voltage, stable operation ability and wide operating tempera?ture. To determine the physical and chemical properties of fluorinated graphene, it is important to control the fluorine nature on graphene. However, there is a challenge for synthesizing and understanding controlled fluorine nature on single layer graphene. In this presentation, we control the fluorine nature on single layer graphene using xenon difluoride with different time in the glove box. **This research was supported by the Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science, ICT and Future Planning (NRF-2016M3A7B 4904328).
