In recent years, researchers from the Massachusetts Institute of Technology and China have developed a capacity-type lithium battery containing molybdenum material, which has higher weight energy density and volumetric energy density than conventional commercial batteries.
Due to its high strength, high melting point, corrosion resistance and wear resistance, molybdenum has been used in steel, chemical, electrical, pharmaceutical and agricultural fields. China is the country with the most abundant molybdenum resources in the world.
Tungsten is a rare high melting point metal in nature with a melting point of up to 3,410 ° C. It has high density, high hardness, high wear resistance, high electrical conductivity and high temperature strength.
Tungsten alloy weights have a long history of development. China has entered the heyday of bronze castings between 1700 and 1000 BC, and the process has reached a fairly high level. Europe also began producing counterweights around the eighth century.
Recently, the China Tungsten Industry Association held a symposium of leaders of tungsten enterprises (groups) in Ganzhou. The meeting unanimously agreed that the participating tungsten enterprises (groups) will jointly maintain the supply order of the tungsten raw material market.
Average content of molybdenum in the earth's crust is 0.00011%, and the global reserves of molybdenum resources are about 11 million tons. Molybdenum has the advantages of high strength, high melting point, corrosion resistance, wear resistance and the like, and is widely used in steel, petroleum, chemical, electrical and electronic technology.
The attributes of China's resource-consuming countries are too strong, and the attributes of resource-producing countries are often overlooked. China's vast land and resources, in terms of mineral resources, is the world's largest leader, tin, gallium, antimony, rare earth, tungsten, molybdenum etc.
