Contemporary Amperex Technology Co., Ltd. (CATL), one of China’s leading automotive lithium-ion battery producers, has revealed a new battery that will help battery electric vehicles with driving ranges of over 1,000 kilometers on a full charge. Dubbed the third generation of CTP (cell-to-pack) technology, the CTP 3.0 battery pack is claimed to have a volume utilization capacity of about 72 percent. In addition, the battery pack has an energy density of 255 Wh/kg for a ternary battery system. Hence offering the highest integration level ever in the world according to CATL.
The battery is named after a legendary creature named ‘Qilin’ in Chinese mythology, reports Xinhua news agency.
According to CATL, Qilin batteries are expected to go into mass production and hit the market in 2023.

By directly integrating cells into packs without modules, CTP technology improves system energy density, simplifies manufacturing and helps reduce costs. In addition, the CTP 3.0 battery has improved service life, safety, charging speed and low temperature performance.
The product’s full-life-cycle reliability and resistance to shock and vibration are improved by the integrated power unit, which is composed of a cell and a multifunctional elastic interlayer.
The battery boasts thermal stability and safety, and is therefore compatible with materials of higher energy density in product upgrades.
Under extreme conditions, the cell can be rapidly cooled, thus preventing abnormal thermal conductivity between cells. At the same time, charging in fast mode takes only 10 minutes.
