A unique MoS2@graphene nanocable with a novel contact model between MoS2 nanosheets and graphene has been developed for high-performance lithium storage.

Advancement in Layered Transition Metal Dichalcogenide Composites for Lithium and Sodium Ion Batteries

“…The deposition of L-TMD NSs on the surface or within the CNT, [42][43][44][45] carbon nanotube/fibers [48][49][50] and amorphous/other form of carbon [92][93][94][95][96][97] [49]. The performance of nanostructured electrodes in LIBs is largely undermined by two key issues which are (1) low conductivity and (2) high volume expansion.…”

Engineering Graphenes from the Nano- to the Macroscale for Electrochemical Energy Storage

“…In these strategies, an external force or specific environment was used to make the assembly of graphene occur, and different internal forces, such as π-π interaction, electrostatic interaction, or chemical bonding, provide the conditions to cause the graphene to be arranged in an oriented direction and linked together to form a specific structure or morphology. Spinning is widely used for manufacturing polymer fibers, and research has extended this method to prepare 1D continuous graphene-based fibers [15]. Neat macroscopic graphene fibers with high mechanical strength and electrical conductivity can be fluidly spun from GO suspensions on a large scale using the wet-spinning technique followed by chemical reduction.…”

“…Graphene nanostructures, formed during the assembly of graphene nanosheets, generate more promising properties that are favorable for energy storage, such as continuous ion diffusion and an electron transfer network and well-designed pore structure [13,14]. Furthermore, graphene macroforms combined with a well-designed monolith shape with different dimensions and nanostructures inherit the excellent properties of the graphene nanosheets and generate new unique characteristics from the nanostructure design [15][16][17]. Therefore, compared with conventional carbon materials, graphene-derived carbons in one, two, or three dimensions with well-controlled nanostructures have more potential in future high-performance EES applications due to the rationally arranged sheets and the performance inherited from them.…”

Nanostructured electrode materials for lithium-ion and sodium-ion batteries via electrospinning

“…In addition, Zhao et al [178] and Yu et al [179] prepared electrospun MoS 2 nanoflakes and WS 2 nanoplates dispersed in CNFs, respectively. To further improve the structural stability and electronic conductivity, Zhi's group presented preparation of SnS 2 @graphene nanocables [180] and MoS 2 @graphene nanocables [181] as anode materials for LIBs. In the typical fabrication process, a PVP solution containing metal source (i.e., Sn and Mo) and tetraethylorthosilicate (TEOS) was first electrospun to form composite nanofibers.…”
