▎ 摘  要

The present paper describes the excellent input performance of graphene-like graphite (GLG) as a negative electrode material for the lithium ion batteries (LIBs), which should allow a new rapid charging method. We find that the GLG electrode can be fully charged only within several minutes by the constant voltage mode, i.e., without resorting to the constant current mode, during which the maximum current reaches as high as ca. 80 A g(-1). No evidence is observed for the lithium metal deposition on the GLG electrode, despite the rapid charging at the voltage below the lithium deposition potential. These characteristics have never been achieved by graphite, currently used as the negative electrode material in LIBs. The GLG-based negative electrode should not only provide a safe and rapid charging method but also facilitate the battery control of LIBs.
