摘要：
CrO3-graphite intercalation compounds (GICs) with various stage numbers (3, 6 and 11) were prepared by a solvent method in acetic acid and their discharge characteristics were investigated comparatively in a DMSO solution Containing 1 mol.dm(-3) LiClO4. On the discharging curves at a low current density (c.d.) of -10 mu A.cm(-2), two potential plateaus appeared at about 2.7 and 1.5 V. The length of the former plateau decreased with the stage number of a GIC. The transition between these two plateaus was likely determined by a kinetic factor even at this low c.d.
