碩士 === 國立臺灣師範大學 === 化學系 === 104 === The aluminum-ion battery (AIB) has been demonstrated recently based on the materials of Al foil anode, graphite cathode, and ionic liquid electrolyte, which show promising features, including low-cost electrode materials, low flammability, three-electron redox reaction, high-rate charging, and long cycle life. Here, we present the performance of aluminum-ion battery with graphite materials in multiple different microstructures. Six different kinds of micro-graphite materials are rendered—SP-1 natural flake graphite, GNPs(Graphene nanoplatelets), KS6, MCMB(Mesocarbon microbeads), Osaka graphite, and thermal-annealed sucrose. The six types of graphite materials were carefully examined under the X-ray diffraction, Scanning electron microscope, and Raman spectroscopy, and have revealed difference in graphite layers, individual sizes, crystallinity, and defect level, which dominate the electrochemical performance of the aluminum-ion battery.
