Tungsten Disulfide WS2 as Battery Material
Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for graphene powder.
The advent of sodium batteries is expected to alleviate the current constraints of lithium resource shortage on the rapid development of the new energy industry, and will further stimulate the application of transition metal disulfide such as tungsten disulfide WS2 in the field of power energy storage.
Lithium-ion batteries are a key raw material for developing energy devices and realizing the vision of "carbon neutral". However, at present, the capital investment in the raw material end is difficult to cover the rapidly growing energy demand, and there is an obvious structural imbalance in the investment in the lithium electric industry chain, which leads to the rising cost of lithium raw materials.
As a result, sodium batteries began to enter the field of vision. Sodium is abundant in nature, and as an energy material, it also has a large capacity and high-rate performance, which can effectively make up for the shortcomings of lithium-ion batteries in the current energy storage field. Although the price of sodium battery will be higher than lithium battery due to the small scale of the supply chain at present, with the maturity of technology, the cost-effective sodium battery will be an effective supplement to lithium battery, and it is even expected to serve the development of new energy field together with a lithium battery.
Tungsten disulfide, as a potential battery material, is also expected to benefit from more market replenishment.
Tungsten disulfide is a layered material with remarkable surface effect, electron fluidity, thermochemical stability, and high density of electron states. It has been widely used in lithium and sodium storage. For example, nanocomposites used as conductive additives or graphene composite as anode material of batteries can show higher specific capacity and discharge efficiency, making up for the deficiency of single component WS2 or C as anode material.
Graphene is a new anode material most studied by energy storage researchers in recent years. It has many advantages, such as excellent electrical and thermal conductivity, a large specific surface area, and so on. However, as an energy storage material, it still compensates for its own defects, such as the material is prone to structural collapse under a long cycle, which will lead to a serious decline in battery capacity. Therefore, graphene and WS2 nanomaterials with high thermochemical stability can effectively compensate for the shortcomings of graphene.
In general, tungsten disulfide is an ideal choice for battery materials.
