However, to achieve practical application of MoS 2 in the energy sector, many issues still need to be addressed. First of all, the surface energy of MoS 2 itself is large, and makes it easy to stack and agglomerate, thereby reducing the activity.
The improvement of the electrical conductivity and exposure of more active sites plays an important role to improve the electrocatalytic performance of MoS 2. However, the low intrinsic conductivity and restacking of the layered interfaces limit the performance of MoS 2 for energy conversion and storage applications 30.
Rational construction of layered MoS 2 nanostructures (nanotubes, nanosheets, nano-flowers) for morphological control and composite of other carbon-based materials is an effective way to develop high-performance energy storage electrode materials.
Due to the tunable density of states, 2D MoS 2 provides electric field-induced doping and, combined with a graphene interface, leads to a high carrier mobility. The fabricatedsolid-state energy storage deviceis obtained using a gel electrolyte that provides an electrochemical capacitance of 1.8 mF/cm 2.
MoS 2 finds two primary applications in energy storage: batteries and supercapacitors. Owning to the layer structure, low resistivity, high electrochemical activity and high stability, it is a good anode material for the LIBs and SIBs, which greatly enhance the performance and safety of the batteries.
The yttrium-doped MoS 2 acts as a metallic buffer that improves charge carrier transfer from the metal electrode to semiconducting MoS 2. With this approach, we fabricate self-aligned, 10-nm-channel-length MoS 2 field-effect transistors on two-inch wafers with an average contact resistances of 69 Ω µm and total resistances of 235 Ω µm.
