The lithium-ion battery is an essential raw material for the development of energy devices and achieving the goal to be carbon neutral. However, the current capital investment in the raw materials end is not sufficient to meet rapidly increasing energy demand. Additionally, there is a clear structural imbalance in the investment made in the lithium electric sector chain. This leads to rising prices for lithium raw material.
sodium cells entered the field of vision. As an energy material, sodium is abundant in nature. It also has high capacity and high rate performance which can compensate for the limitations of lithium-ion cells in the energy storage sector. Despite the fact that sodium battery is more expensive than lithium battery because of its smaller supply chain, sodium battery with mature technology will still be an effective replacement for lithium battery. In fact, it can even be used to develop new energy fields with lithium battery.
Tungsten Disulfide will also benefit from increased market replenishment as a potential material for batteries.
Tungsten dioxide is a layered metal with amazing surface effects, electron fluidity, thermochemical stability, and high densities of electron states. It has been used extensively in sodium and lithium storage. As an example, nanocomposites that are used as conductive additions or graphene-composite as anode for batteries can have a higher specific capacity and discharge rate than single components WS2 and C.
Graphene, a novel anode material, has been a focus of energy storage researchers for many years. It is a versatile anode material with many advantages such as high electrical and thermal conductivity, large specific surface area and so forth. Although it is an energy storage medium, it does not compensate for its own flaws. For example, the material is susceptible to structural collapse during a long cycle which can lead to a severe decline in battery power. Graphene, WS2 and other nanomaterials can be used to compensate for the graphene’s weaknesses.
In general, tungsten dioxide is a good choice for battery materials.
