▎ 摘  要

NOVELTY - An AA' stacked graphite comprises graphene stacked in the sequence of AA' in which alternate graphene layers exhibiting AA' stacking are horizontally translated by a half hexagon (1.23 Angstrom ) from zigzag AA stacking of graphene layers. USE - An AA' stacked graphite used as electrode material for secondary battery and flexible display, hydrogen storage material, or matrix for graphite intercalation compounds (GICs) by intercalation of other elements. ADVANTAGE - The AA' stacked graphite has a larger interplanar spacing (i.e., an interplanar distance between graphene layers) ( approximately 3.44 Angstrom ) than that of an AB stacked graphite ( approximately 3.35 Angstrom ). As a result, the graphene layers stacked in the AA' manner can be easily separated from each other and have a unique electric characteristic.
