When cobalt is hyped up, everybody will go for cobalt-free; if nickel is hyped up, every person will not want nickel, but lithium is still there. "Lately, Zeng Yuqun, chairman of Ningde Times, revealed one more vital details when talking about the cost boost of upstream raw materials at the firm's 2020 annual general conference of investors. The sodium battery modern technology is mature and related items will certainly be launched in July.
As soon as the information was released, it immediately triggered a warmed conversation in the industry. How is the development of my nation's salt battery sector? Will it rebuild the current market structure dominated by lithium batteries?
A sodium battery is a rechargeable battery that utilizes salt ions (Na+) as a charge carrier, mostly depending on the activity of sodium ions in between the positive and unfavorable electrodes to work, and its principle is similar to that of lithium batteries.
Actually, salt batteries are not new. As early as the 1970s, research on sodium batteries was carried out nearly at the same time as lithium batteries. Nevertheless, because of research conditions and other reasons, the advancement was stagnant. At the same time, lithium batteries are quickly advancing, as well as they have actually promptly accomplished comprehensive coverage in the fields of electronic intake, computer systems, interaction networks, and also electrical lorries.
Today, the increasing rates of battery basic materials have actually brought huge stress to the swiftly developing power battery firms. The information shows that the ordinary place cost of lithium carbonate has to do with 89,000 yuan/ton, up about 67% from the beginning of the year; the typical place rate of lithium hydroxide is about 89,500 yuan/ton, up 80% from the get go of the year. The reason for the rate boost is generally because of the surge in demand in both major markets of electric lorries and also power storage.
About 70% of the world's lithium sources are concentrated in South America, as well as 80% of my country's lithium sources are imported. In order to address the "stuck neck" trouble of lithium resources, appropriate firms have actually transformed their focus to salt batteries. It is comprehended that the electrode materials made use of in sodium batteries are generally salt salts, which have more plentiful books and lower prices than lithium salts. "Sodium chloride can not be fried since there is a great deal of salt." Zeng Yuqun said.

"Sodium chloride can not be fried since there is a great deal of salt." Zeng Yuqun said.
" Sodium batteries can make use of the existing lithium battery products, cell production processes and production devices, and there is no obvious traffic jam in mass production." Hu Yongsheng, a scientist at the Institute of Physics, Chinese Academy of Sciences, told press reporters that sodium batteries have progressively relocated from laboratory to useful application. At present, China has been at the forefront of the world in the advancement as well as manufacture of sodium battery products, standard solution, and also advertising and application, as well as the market will soon be marketed.
So, will salt batteries overturn the prominence of lithium batteries in the future? From the demand side, the market's demands for power batteries can be separated into four measurements, particularly, being able to meet higher ability, quicker billing rate, more secure and also lower price. It is understood that the current energy density of salt batteries is 90-150Wh/ Kg, compared with 150-180Wh/ Kg of lithium iron phosphate batteries and 200-280Wh/ Kg of ternary lithium-ion batteries, there is still a large space. Yet at the same time, salt batteries are not inferior in regards to charge and also discharge price performance, high and low temperature level efficiency, and also cycle efficiency, and also even have a lot more benefits. Furthermore, salt ions use less or practically no rare metals, and affordable aluminum foils can be utilized for both the positive and also adverse existing collection agencies, which can even more reduce prices while boosting battery safety and security.
Nonetheless, the affordable of resources supply does not suggest that the expense of sodium batteries is lower. "Salt batteries are not inexpensive as quickly as they are introduced. The current supply chain is still small and immature, as well as might be more expensive than lithium batteries." Zeng Yuqun claimed that salt batteries still require an advancement procedure.
Xie Honghe, principal of the color sector at the Zhongtai Securities Research Institute, additionally mentioned that the industrial application of sodium batteries still faces a collection of issues, consisting of the stability of electrolytes, electrodes and also electrolyte user interfaces, as well as the recyclability of relevant sectors and waste batteries needs to be further studied and also settled.
In the eyes of sector insiders, lithium-ion batteries are still the mainstream modern technology path of power batteries for brand-new energy automobiles in the future.
"The international lithium resource reserves can meet the growth demands of brand-new energy lorries, as well as the efficiency of lithium ion batteries is better." Xie Honghe thinks that the future application circumstances of salt batteries might be concentrated in the fields of power storage, low-speed brand-new energy automobiles, as well as little power, and can not entirely change lithium Application of batteries in new power automobiles.
Hu Yongsheng further introduced that salt battery products will be mostly made use of in circumstances below 150Wh/kg, offering power storage batteries with large temperature array, much safer, higher price and also lower cost, which can be used as an useful supplement to support as well as ensure the advancement of lithium batteries. To a particular extent, the restricted development of energy storage batteries triggered by the lack of lithium sources will be relieved, and lead-acid batteries will be gradually replaced. In his sight, salt batteries are presently positioned as the most affordable and also high-safety power storage batteries, as well as it is anticipated that they can reach the rate of lead-acid batteries and also the performance of lithium batteries after being scaled up.
It deserves mentioning that the "Guiding Viewpoints on Increasing the Growth of New Power Storage (Draft for Remark)" collectively issued by the National Development and Reform Commission and the National Power Administration mentioned that it is necessary to follow the diversification of energy storage space modern technologies and also accelerate the growth of flywheel energy storage space and also salt batteries. and also various other technologies to carry out large test demonstrations. This is likewise the very first time that sodium batteries have been written into the nationwide development strategy as well as have been "sustained" by the plan.
