Due to the limited global reserves of lithium resources (lithium element in the earth’s crust content of only 0.0065%), resulting in the current lithium ore and lithium materials transaction prices are very high, and even Guangqi Group Chairman Zeng Qinghong said that car manufacturing is “to work for CATL.
In addition, the existing lithium-ion battery energy density is close to the theoretical limit, with the current mainstream lithium iron phosphate battery energy density of 200Wh/kg or less, and ternary lithium battery energy density of 200-300Wh/kg between. In this case, scientists have come up with another metal material — sodium.
Sodium in the earth’s reserves ranked sixth and has similar chemical properties to lithium, but due to the energy density of the disadvantage, the development of sodium-ion batteries is still in the eve of mass production, at least the need for new materials in sodium storage, new electrolyte breakthroughs.
Of course, all major companies have already aimed at this field, at least CATL, BYD, Hive Energy, Yiwei Lithium Energy, Chongming Battery, Xin Wanda, Guoxuan High-tech, Fu Energy Technology and other manufacturers are involved.
In the industry’s view, 2023 may become the first year of mass production of sodium-ion batteries, before sodium in science and technology, Chuangyi Technology, Peng Hui Energy, Fu Energy Technology, Huayang shares and many other companies have announced in 2023 to enter the industrialization stage.
WKT said today that its sodium battery project will start mass production by the end of June 2023, and it has docked intended customers, but no orders have been signed yet.
It is reported that WKT is an A-share listed company with new energy lithium battery as its main business and 3C digital battery and power battery as its core business, and its stock was listed on Shanghai Stock Exchange in 1998, abbreviated as “WKT”.
