The interpenetrated carbon nanosheets embedded with the MoO2 nanocrystallines (NCs) are self-assembling to a novel three-dimensional (3D) structure by a facile method. During the growth process, the MoO2 NCs induce the dopamine monomer to form polydopamine nanosheets, which construct the 3D framework and are further carbonized. It is worth noticing that MoO2 NCs with the size of 5 nm are uniformly loaded on the interpenetrated carbon nanosheets. More importantly, the design of this special 3D structure can contribute to enhancing the electrochemical performances owning to its large specific area and high electronic conductivity, which lead to not only higher capacity of 983 mA h g−1 after 200 cycles, but also better reversibility and rate capacities. These excellent electrochemical performances suggest that the unique 3D composite can act as a promising anode candidate for high-performance lithium-ion storage.
