Chinese battery manufacturer CATL has introduced three new battery systems at its Super Tech Day event. The focus was on the so-called Naxtra battery, which the company claims is the first sodium-ion battery ready for mass production. According to CATL, the cell achieves an energy density of 175 watt-hours per kilogram, which is in the range of todayʼs LFP cells. The battery is said to deliver 90 percent of its power at minus 40 degrees Celsius and allows more than 10,000 charge cycles. CATL plans to begin production of this cell in December 2025.
Shenxing battery
The second generation of the Shenxing battery was also introduced, which, according to the manufacturer, can be charged at a rate of up to 12C for short periods of time. This would result in a maximum charging capacity of 1.3 megawatts for an electric vehicle battery pack. In laboratory tests under controlled conditions, the LFP cells have reportedly enabled a range of 800 kilometers and could be charged from five to 80 percent within 15 minutes at minus ten degress Celsius.
Freevoy Dual-Power Battery
With the so-called Freevoy Dual-Power Battery, CATL is presenting a system that combines two separate energy zones in one battery system. The company considers this an answer to different requirements such as suitability for everyday use and range. The battery architecture has a modular design and, according to the manufacturer, allows the combination of different cell chemistries – such as sodium-ion cells and LFP cells or NCM cells.
