December 15 news, recently australian Adelaide University researchers published a paper, announcing a breakthrough in metal sulfur battery technology. Professor Qiao Shizhang, director of the University's Center for Energy and Catalytic Materials, said that researchers have catalyzed battery reactions through new high-efficiency electrode materials and improved the durability of metal-sulfur batteries.

Under the same weight, the energy of metal sulfur batteries can reach more than twice that of the current generation of lithium batteries, and the number of cycles of charge and discharge can reach 10,000 times. In terms of price, Qiao Shizhang said that the cost of sodium thiode batteries is much cheaper than lithium batteries, and it can become the mainstream energy source for electric vehicles, mobile phones, laptops and other electronic products in the future, and it is very environmentally friendly. Qiao Shizhang expects that within 5 to 10 years, they will be able to find a way for metal sulfur batteries to be feasible at both the technical and economic levels.
After the rise of the electric vehicle industry, supply chain manufacturers that were not well known to the public came to the front, such as the Ningde era, which is now almost a well-known battery company. At present, the vast majority of electric vehicles use lithium batteries, the energy density of lithium iron phosphate batteries with high safety can reach 180Wh/kg, and the energy density of ternary lithium batteries can reach 240Wh/kg, which can ensure that electric vehicles can last more than 400 kilometers.
The problem is that lithium batteries are susceptible to environmental influences and will be greatly reduced in winter. Some time ago, Russian Industry Minister Dennis Manturov complained about his Model 3, making him almost unable to return home. Therefore, many companies are researching new materials.
Some time ago, catheter era released the first generation of sodium-ion batteries, which can ensure more than 90% of the battery energy efficiency in the environment of minus 20 ° C, but the energy density is only 160Wh/kg, which is far inferior to ternary lithium batteries. Moreover, the service life of sodium-ion batteries is only half that of ternary lithium batteries, which is certainly difficult to commercialize for the time being.
The amount of sodium on Earth is more than 400 times that of lithium, and if sodium-ion batteries can be switched to, the price of electric vehicles and other electronic products will drop significantly. The metal proposed by the University of Adelaide in Australia is most likely lithium or sodium, and from the example of Qiao Shizhang's sodium sulfur battery, the probability of sodium is higher.
The Ningde era and the University of Adelaide in Australia also chose sodium-ion batteries, but the direction is different, and the main choice should be the electrode material. CATL can learn from the experience of the University of Adelaide in Australia and improve its own battery design.
At present, THE NINGDE era is the world's largest battery company, pressing LG, Panasonic, BYD, etc., but the NINGDE era can not be taken lightly, once the technology lags behind, it is only a matter of minutes to be eliminated.
