Lithium-ion batteries are used in our cell phones and laptops. Now, a lithium-air battery has become the "future battery" in the eyes of scientists.
The reporter learned yesterday that Wuhan scientists from the Wuhan University of Science and Technology-Harvard University Nano Joint Key Laboratory are generating enough power for the battery. Their research attracted the attention and positive evaluation of Prof. Weiting Han, who made the world's first lithium battery. His latest results were published online on the 12th of this month in the internationally renowned journal PNAS.
For years, researchers have been hoping to use lithium-air batteries instead of traditional lithium-ion batteries because lithium-ion batteries have more than 10 times more power than the best-performing lithium-ion batteries.
In 2009, Prof. Ma Liqiang, who was introduced by Wuhan University of Technology, took the lead, Wuhan University of Technology and Harvard University set up a joint nano-key laboratory. Mai Liqiang introduced that lithium-air batteries have been rapidly developed in recent years with large capacity and large energy density electrochemical cells.
It is understood that the principle of lithium-air battery power generation is the oxidation of lithium metal to produce lithium ions and electrons, lithium ions, electrons and oxygen molecules in the air to carry out the reduction reaction, thereby generating electricity.
Because air is readily available, people can make lithium-air batteries lighter and smaller without having to worry about fuel storage space. (Reporter Li Jia)
Silicon carbide has the advantage of stable chemistry performance, high thermal conductivity, low coefficient of thermal expansion and good abrasive resistance. Silicon Carbide Abrasive Cloth usually used for grinding floor, stone, glass and metal.
Abrasive Cloth is the cloth with grinding compound. According to the different grinding compound, the abrasive cloth can divided into four kinds: Aluminum Oxide Abrasive Cloth, silicon carbide abrasive cloth, Zirconium Oxide Abrasive Cloth and Calcined Aluminum Oxide Abrasive Cloth and so on. According to the hardness, it also can be divided into flexible abrasive cloth,middle flexible abrasive cloth and hard abrasive cloth. Some of them can do waterproof or oil-proof. The shape of the abrasive cloth is roll, belt and sheet. The abrasive cloth is generally used for wood grinding and metal grinding. It can available in vary grits.
After 30 years` development, abrasive cloth grinding has become a complete and self-contained system of new processing technology. Because of its high processing efficiency, wide application range, strong adaptability, low cost, safe and convenient operation, it is well received by customers. In foreign countries, Abrasive Belt grinding technology has made great progress. It can be applianced for more and more processing object . It can process almost all engineering materials, from the general daily life appliance to application of large aerospace equipment.
