| 제목 | Remarkably Stable Composites of Graphene and Ni−Al Layered Double Hydroxide for Electrochemical Capacitor Electrodes |
| 초록 | Graphene/Ni−Al layered double hydroxide (LDH) hybrid materials were synthesized by a hydrothermal reaction. Hexagonal Ni−Al LDH particles nucleated and grew on graphene sheets, thus preventing restacking of the graphene sheets and aggregation of the Ni−Al LDH nanoparticles upon drying. Electrode made from the graphene/Ni−Al LDH hybrid materials showed a substantial improvement in electrochemical capacitance relative to those made with pure Ni−Al LDH nanoparticles. In addition, the graphene/Ni−Al LDH hybrid composite materials showed remarkable stability after 4000 cycles with over 100% capacitance retention. These materials are thus very promising for use in electrochemical capacitor electrodes. Reference: S.-I In, 2013. Journal of Electrochemical Science and Technology, 4(1), pp.19-26. |
