DETROIT – The third generation of CATL’s cell-to-pack (CTP) technology offers a range of over 621 miles (1000 km) on a single charge. CATL will start mass production of its latest generation product, Qilin, next year, the company announced.
Qilin, named after a legendary creature in Chinese mythology, also offers a record-breaking volume utilization efficiency of 72 percent and an energy density of up to 416 kilojoules per pound (255 Wh/kg); it achieves the highest integration level worldwide so far.
With the same chemical system and the same pack size, Qilin delivers 13 percent more power than the 4680 battery, accomplishing an all-around improvement in range, fast charging, safety, service life, efficiency, and low-temperature performance.
CATL have integrated an internal crossbeam, liquid-cooling plate, and thermal pad into a multifunctional elastic interlayer in Qilin.
Qilin also features built-in micron bridges inside the interlayer, which flexibly accommodates the changes inside the cell, thus improving the battery’s reliability throughout its entire life cycle. The integrated energy unit, composed of the cell and the multifunctional elastic interlayer, builds a more stable load-bearing structure perpendicular to the driving direction, thus enhancing the shock and vibration resistance of the battery pack.
