▎ 摘  要

Multilayer graphene (MLG) is a promising material for anodes of next-generation thin-film rechargeable batteries. The inverted layer exchange using an Fe catalyst allowed for the low-temperature (600 degrees C) self-organization of the anode electrode structure, that is, an active material (MLG) on a current collector (Fe). A coin-type cell, fabricated from the MLG electrode and pure Li metal foil, showed distinct peaks, indicating Li intercalation into the MLG in a cyclic voltammogram. After 100 charge/discharge cycles, the capacity was 3.3 mu Ah cm(-2) and coulombic efficiency was 98%. The low-temperature synthesis of a MLG anode structure and its operation were demonstrated.
