It is still challenging to develop anode materials with high capacity and long cycling stability for lithium-ion batteries (LIBs). To address such issues, herein, for the first time, we present a three-dimensional and freestanding ReS 2 /graphene heterostructure (3DRG) as an anode synthesized via a one-pot hydrothermal method. The hybrid shows a hierarchically sandwichlike, nanoporous, and conductive three-dimensional (3D) network constructed by two-dimensional (2D) ReS 2 /graphene heterostructural nanosheets, which can be directly utilized as a freestanding and binder-free anode for LIBs. When the current density is 100 mA g −1 , the 3DRG anode delivers a high reversible specific capacity of 653 mAh g −1 . The 3DRG anode also delivers higher rate capability and cycling stability than the bare ReS 2 anode. The markedly boosted electrochemical properties derive from the unique nanoarchitecture, which guarantees massive electrochemical active sites, short channels of lithium-ion diffusion, fast electron/ion transportation, and inhibition of the volume change of ReS 2 for LIBs.

a b s t r a c tBackbone connectivity is a critical and challenging problem in vehicle ad hoc networks. Just like base stations in cellular networks, the backbones or mobile base stations in vehicle ad hoc networks play important roles in location management and engineering applications. In this paper, we discuss the one-to-one connectivity by extending the navigation functions, and present the integrated power and mobility navigation functions. Considering the interference between the backbones, we describe the interference alleviating navigation function design. We establish the control laws, describe the numerical computation, and discuss the stability of the navigation system at the end.
