An “atomic layer‐by‐layer” structure of Co 3 O 4 /graphene is developed as an anode material for lithium‐ion batteries. Due to the atomic thickness of both the Co 3 O 4 nanosheets and graphene, the composite exhibits an ultrahigh specific capacity of 1134.4 mAh g −1 and an ultralong life up to 2000 cycles at 2.25 C, far beyond the performances of previously reported Co 3 O 4 /C composites.
