Magnesium metal production technology has been put on the agenda by the Ministry of Industry and Information Technology. Potential Super Lithium Battery? A list of individual stocks in the industrial chain

Recently, affected by the downstream demand of various industries, resource stocks continue to heat up. In some industries, new solutions are also emerging. Yesterday, in response to proposal No. 0899 of the fourth session of the 13th National Committee of the Chinese people's political Consultative Conference, the Ministry of Industry and Information Technology said that in the next step, it will continue to work with relevant departments to further strengthen scientific and technological support work such as efficient development and comprehensive utilization of salt lake resources, and guide localities and enterprises to do a good job in the demonstration of chlorine products. It is mentioned that the technology of producing metal magnesium by anhydrous magnesium chloride electrolysis will be carried out. To promote and solve the technical problems perplexing the development and utilization of salt lake resources.

Coincidentally, on Friday, the China Nonferrous Metals Association, the magnesium Branch of the China Nonferrous Metals Industry Association, and the magnesium Alloy Branch of the China Materials Research Association will also hold the first symposium on magnesium batteries and their key materials in Chongqing from August 27 to 28, 2021.

According to the Polaris Energy Storage Network, magnesium batteries have been considered to have great potential to surpass lithium-ion batteries since they were launched in 2000, mainly because magnesium metals with low price, high volume capacity and non-dendritic growth behavior can be directly used as battery negative electrodes. But the development of this technology has been very slow.

Recently, the research team of Professor Yao Yan of the University of Houston in the United States, in conjunction with the North American Toyota Research Center, made a major breakthrough in the field of magnesium batteries, discovered a positive reaction mechanism that can quickly store Mg2+ ions, and invented a magnesium electrolyte based on ether mixed solvents and weak coordination anions, so that magnesium can be deposited without dendrite at high current density. The maximum output power of the magnesium battery is almost two orders of magnitude higher than that previously reported.

Magnesium is less active than lithium. At the same time, the melting point of lithium is about 180 degrees Celsius, and the melting point of magnesium is about 650 degrees Celsius, so it is safer. And magnesium is much more abundant than lithium on earth.

It is worth noting that the price of magnesium has also risen recently, up 30% from four months ago.
