CATL launches third technology of cell-to-pack; 72% quantity utilization effectivity, as much as 255 Wh/kg


CATL launched Qilin, the third technology of its CTP (cell-to-pack) know-how. With a record-breaking quantity utilization effectivity of 72% and an vitality density of as much as 255 Wh/kg, it achieves the best integration degree worldwide up to now, able to delivering a variety of greater than 1,000 km.


With the identical chemical system and the identical pack dimension, the Qilin CTP can ship 13% extra energy than the 4680 battery.

In 2019, CATL launched the world’s first module-less battery pack CTP, taking the lead in reaching a quantity utilization effectivity of 55%. Along with general breakthroughs within the core course of, algorithm and supplies, CATL is redefining battery construction design with “Qilin,” which is called after a legendary hooved chimerical creature in Chinese language mythology (generally referred to as the Chinese language unicorn, and symbolizing good luck and prosperity).

  • Perform Integration. Within the CTP 3.0 battery, the interior crossbeam, liquid-cooling plate and thermal pad have been built-in right into a multifunctional elastic interlayer. It additionally options built-in micron bridges contained in the interlayer, which flexibly accommodate the modifications contained in the cell, bettering the battery reliability all through its full life cycle.

    The built-in vitality unit, which consists of the cell and the multifunctional elastic interlayer, builds a extra secure load-bearing construction perpendicular to the driving course, thus enhancing the shock and vibration resistance of the battery pack.

  • Reshaping system construction. Powered by its exact computing and AI simulation capabilities, CATL explores the boundaries of battery design involving the battery’s full life cycle software eventualities. The underside-sharing design permits the sensible association of varied elements together with structural safety, high-voltage connection and a protecting vent for thermal runaway, additional rising the battery capability by 6%. In the meantime, the CTP 3.0 battery satisfies the factors of the battery security exams required by nationwide requirements such because the bollard take a look at.

  • Disruptive Water Cooling Design. By inserting liquid cooling useful components between adjoining cells, the large-surface cell cooling know-how will increase the warmth switch space by 4 instances, cuts thermal management time in half, and helps a scorching begin in 5 minutes and quick charging in 10 minutes. It permits the cell to chill down quickly in excessive circumstances, successfully stopping irregular thermal conduction amongst cells. Furthermore, it has achieved thermal stability and thermal security for all chemical programs, making it suitable with supplies with larger vitality density.

Supported by the above-mentioned technological improvements, the CTP 3.0 battery can improve the vitality density to 255 Wh/kg for ternary battery programs, and 160 Wh/kg for LFP battery programs. With the identical chemical system and the identical pack dimension, it may possibly ship 13% extra energy than the 4680 battery, undertaking an all-round enchancment in vary, fast-charging, security, service life, effectivity and low-temperature efficiency.

The CTP 3.0 batteries, or Qilin, are anticipated to be mass produced and are available available on the market in 2023.
