[cost advantage no longer, supply chain imperfect sodium battery "get on the car" less than expected. FIFA, May 31, the popular "first year of mass production of sodium battery", the market development does not seem to be as smooth as expected. On the demand side, very few models were confirmed to be equipped with sodium batteries during the year. At present, only Chery iCar, Sihao Flower Fairy and Jiangling Group New Energy EV3 have announced plans for sodium batteries to "get on the bus". At the same time, battery-grade lithium carbonate fell back to about 300000 yuan / ton, the cost advantage of sodium battery is no longer prominent. The industrial chain still maintains a high degree of enthusiasm for sodium batteries, research and development, and production are in full swing. Take Vico Technology as an example, the first phase of the company's sodium battery project has been completed and put into production, and the second phase of the project has just begun. Chen Liangqin, director of Vico Technology, told the Shanghai Securities News that the industrial chain is still firmly optimistic about sodium batteries, and the upstream and downstream are working together to explore the possibility of application scenarios. However, Chen Liangqin also pointed out that the sodium battery industry chain is not yet mature, not many manufacturers are really put into production, and it will take at least two to three years for the industry to move towards industrialization.
