The introduction of sodium batteries should alleviate current limitations of the lithium resource scarcity on rapid development in the new energy sector. This will stimulate further the application of transitional metal disulfide like tungsten disulfide (WS2) in the field power energy storage.
Lithium ion batteries form a vital raw material in the development of energy devices. This is essential to achieve “carbon neutral” and other environmental goals. It is not possible to invest in capital in raw material to support the rapid growing energy demands. Additionally, there are obvious structural inequalities in investments in the lithium electric sector chain. This leads to rising prices for lithium raw materials.

Sodium batteries entered the field of vision. As an energy material, sodium has high capacity and high performance. This can make up the deficiencies of current lithium-ion cells in energy storage. While sodium batteries will cost more than lithium batteries because of their small size, they are cheaper than lithium. With the maturation of technology, sodium battery is expected to become a viable alternative to lithium batteries.

Tungsten Disulfide will benefit as well from additional market replenishment.
Tungsten dioxide is a layer material that exhibits remarkable surface effects and electron fluidity. It is widely used for lithium and sodium storage. As an example, nanocomposites that are used as conductive additions to batteries or as graphene composites as anode materials for them can have a higher specific capacity or discharge efficiency than single components WS2 and C.

Graphene was a recent anode material, which has been favored by energy storage researchers. It is a versatile anode material with many great advantages such as high electrical and thermal conductivity, large specific area and so forth. Although it is an energy storage medium, its inherent defects can be compensated for. The material is vulnerable to structural collapse over a prolonged cycle which could lead to serious reductions in the battery’s capacity. High thermochemical stability graphene or WS2 nanomaterials are able to effectively offset the flaws of graphene.
In general, tungsten dioxide is the best option for batteries.
