| 中文摘要 | Thin-film electrodes of graphene nanoplatelets (GNPs) were fabricated through the electrostatic spray deposition (ESD) technique. The combination of a binder-free deposition technique and an open pore structure of graphene films results in an excellent power handling ability of the electrodes. Cyclic voltammetry measurements of 1-mu m-thick electrodes yield near rectangular curves even at a very high scan rate of 20 V s(-1). Thin-film electrodes (1 mu m thickness) show specific power and energy of about 75.46 kW kg(-1) and 2.93 W h kg(-1), respectively, at a 5 V s(-1) scan rate. For the thin-film electrode, about 53 % of the initial specific capacitance of electrodes at low scan rates was retained at a high scan rate of 20 V s(-1). Although the thickness of the thin-film electrodes has influence on their rate capability, an electrode with an increased thickness of 6 mu m retained about 30 % if its initial capacitance at a very high scan rate of 20 V s(-1). The results show that the ESD-fabricated GNP electrodes are promising candidates for thin-film energy storage for applications that require moderate energy density and very high power and rate handling ability. |
