The new batteries have a slightly lower density than current lithium-iron-phosphate models, but have different benefits.
CATL, a major Chinese battery manufacturer, has unveiled the first generation of sodium-ion batteries, cnevpost.com says.
For many, this event will be a new round of innovation in this area. However, it is known that their density is somewhat lower than that of modern lithium-iron-phosphate models and amounts to 160 W / kg. But the new batteries have other advantages. First of all, this is performance even at very low temperatures and the possibility of trouble-free fast charging.
Sodium-ion batteries can charge up to 80 percent in 15 minutes at room temperature and still retain more than 90 percent charge, even if the temperature is around -20 ° C. Moreover, they exceeded the safety requirements of the Chinese national standard with excellent thermal stability.
However, the company will not stop there. Already, there are plans to develop a second generation of sodium-ion batteries, which will be able to show a density of 200 W / kg. In the meantime, CATL has already begun to establish production of the existing model, which will probably be able to enter a full series by 2023.
Note that earlier the South Korean tech giant LG was able to overtake CATL in the number of deliveries of batteries for electric vehicles. These are the results of the activities of both companies showed the recent reports for May. The total capacity of batteries on electric vehicles, which were registered in May, amounted to 19.7 GWh, which exceeds last year’s figures by as much as 330 percent.
It is possible that such a lag of the Chinese is due to the preparation of the enterprise for the development of new batteries.
