Figure 8. (A) Schematic of graphene-like carbon (GLC) coating on the Al foil. Reproduced from Ref.^[202] with permission. Copyright 2019, American Chemical Society. (B) Cyclic performance between 3 and 4.3 V at a rate of 1 C (150 mA/g) for 100 cycles. (C) Rate capabilities at various rates of 0.1 C, 0.2 C, 0.5 C, 1 C, 2 C, and 5 C for a total of 28 cycles. The sample named bare represents the bare aluminum foil, whereas 1-Al, 3-Al, and 5-Al represent aluminum foils coated with different layers of graphene, and the numbers 1, 3, and 5 indicate the graphene layers.
