“…231 Based on first-principle calculations, 1T MoS 2 monolayers have been identified as a suitable anode material for lithiumion batteries due to their ability to absorb Li ions at high concentrations without aggregation. 232 T. Xiang et al have realised hybrid 1T MoS 2 /graphene electrodes exhibiting a capacity of 666 mA h g À1 at high current density (3500 mA g À1 ). 233 It is interesting to note that the arrays of vertically aligned fewlayered MoS 2 nanosheets composing the electrodes were grown on graphene via a single-step hydrothermal reaction and the interlayer spacing in thus grown MoS 2 reaches 9.8 Å dictated by the graphene lattice; such lattice expansion facilitates a faster Li diffusion essential for a high performance lithium-ion battery.…”

“…Li insertion into electrodes has been extensively studied Chen et al, 2013;Kan et al, 2014;Xu et al, 2014). Several attempts have been made to predict failure conditions and to elucidate cracks and comminution within battery electrodes in order to suppress cracking (Aifantis and Dempsey, 2005;Li et al, 2011).…”

a b s t r a c tInsertion-induced stress and interfacial decohesion are studied for a silicon thin film adhesively bonded to a rigid substrate under potentiostatic operation. An axisymmetric finite element model with traction-separation law governing the interfacial degradation is used to study the highly nonlinear diffusion-induced volumetric expansion. Plastic yielding of the film, coupling effects between diffusion and stress, diffusion from both the edge and the top surfaces, and concentration dependence of material properties are considered. It is found interface fails in shear mode, and interfacial decohesion initiates at the interface corner and propagates toward the center. A smaller yield stress of the film is beneficial to structural integrity. The side surface and the top surface near the corner are the critical regions for fracture.

“…In addition, their structural flexibility, highly tunable surface, high surface exposure, and both "Faradaic" and "non-Faradaic" electrochemical behaviors (e.g., multilayer ion adsorptions on the surface) make them much useful for flexible and smart devices, and for the improvement of energy density. [17][18][19][20][21][22][23][24][25] Appropriate integration of 2D materials into EES devices could enable the latter to perform various new functions which are highly useful for our daily life. In particular, they have been well used in small integrated devices showing the above advantages.…”
