Atomic Layer‐by‐Layer Co₃O₄/Graphene Composite for High Performance Lithium‐Ion Batteries

Abstract

An “atomic layer-by-layer” structure of Co3O4/graphene is developed as an anode material for lithium-ion batteries. Due to the atomic thickness of both the Co3O4 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 Co3O4/C composites.
