Three-dimensional self-supported nanoarchitectured arrays electrodes (3DSNAEs) consisting of a direct growth of nanoarchitectured arrays on the conductive current collector, including homogeneous and heterogeneous nanoarchitectured arrays structures, have been currently studied as the most promising electrodes owing to their synergies resulting from the multistructure hybrid and integrating heterocomponents to address the requirements (high energy and power density) of superperformance lithium ion batteries (LIBs) applied in portable electronic consumer devices, electric vehicles, large-scale electricity storage, and so on. In the paper, recent advances in the strategies for the fabrication, selection of the different current collector substrates, and structural configuration of 3DSNAEs with different cathode and anode materials are investigated in detail. The intrinsic relationship of the unique structural characters, the conductive substrates, and electrochemical kinetic properties of 3DSNAEs is minutely analyzed. Finally, the future design trends and directions of 3DSNAEs are highlighted, which may open a new avenue of developing ideal multifunctional 3DSNAEs for further advanced LIBs.

The three-dimensional (3D) graphene networks have been prepared by annealing the mixture of graphene oxide and SiO 2 nanoparticles and then etching SiO 2. The obtained material was characterized by X-ray diffraction, scanning electron microscope and transmission electron microscopy, which revealed that 3D networks consisting of crumpled graphene nanosheets were preserved after the removal of SiO 2. When used as anode material of lithium ion batteries, the graphene networks showed a reversible capacity of 610.9 mAh/g at a current density of 50 mA/g after 50 cycles and excellent rate capability of 291.5 mAh/g at a current density of 5000 mA/g. The good electrochemical performance can be attributed to the network structure, which enables graphene to electrochemically absorb more lithium ions and significantly improve the electrical conductivity of electrode. The graphene networks have the potential applications in ultracapacitor and catalyst supports.

A three-dimensional “fin-groove” composite structure copper current collector was fabricated by micro-ploughing process. 3D and common 2D carbon anodes for lithium- ion batteries were prepared. The electrochemical properties of these electrodes were studied by linear sweep cyclic voltammetry (CV) and charge-discharge (C-D) test. 2D anode showed high contact resistance, high coulombic efficiency but poor cycle performance. In contrast, 3D anode showed the structure superiority in reinforcing bonding force between active materials and copper substrate, improving the conductive environment and alleviating volume changes. It was believed that 3D anode can keep high coulombic efficiency and improve the cycle performance of lithium- ion batteries.

N-Doped carbon network encapsulated MnO nanorods demonstrate 95% capacity retention at a current density of 4000 mA g−1for 3000 cycles. In this case, almost no pulverization or size variation of the nanorods can be observed.
