China unveils EV battery with unprecedented 1,000km on single charge

A record-breaking electric vehicle (EV) battery, with an unprecedented volume utilization efficiency of 72 percent, an energy density of up to 255 watt hour/kilogram (Wh/kg), the world's highest integration level, and capable of delivering a range of over 1,000 kilometers on a single charge, was revealed by a Chinese company on Thursday.

The battery, named Qilin after a legendary creature in Chinese mythology, is expected to go into mass production in 2023, said Contemporary Amperex Technology Co., Ltd. (CATL), China's leading automotive lithium-ion battery maker.

In 2019, CATL launched the world's first module-less battery pack cell-to-pack (CTP), taking the lead in achieving a volume utilization efficiency of over 50 percent.

The Qilin battery, or CTP 3.0 battery, with the third generation CTP technology, has a volume utilization efficiency of 72 percent and an energy density of up to 255 Wh/kg for ternary battery systems, giving it the highest integration level in the world, according to CATL.

The battery delivers 13 percent more power than the 4680 battery produced by global EV giant Tesla, with CATL saying it offers improvements in range, fast-charging, safety, service life, efficiency and low-temperature performance.
