CATL launches CTP 3.0 battery "Qilin," achieves the highest integration level in the world
NINGDE, China, June 23, 2022 /PRNewswire-Asianet/ --

On June 23, CATL launched Qilin, the third generation of its CTP (cell-to-pack) 
technology. With a record-breaking volume utilization efficiency of 72% and an 
energy density of up to 255 Wh/kg, it achieves the highest integration level 
worldwide so far, capable of delivering a range of over 1,000 km in a breeze.

Focusing on the very nature of electrochemistry, CATL continues its endeavor to 
push beyond the boundaries of innovations in system structure. In 2019, CATL 
launched the world's first module-less battery pack CTP, taking the lead in 
achieving a volume utilization efficiency of over 50%. Together with overall 
breakthroughs in the core process, algorithm and materials, CATL redefines 
battery structure design with "Qilin," which is named after a legendary 
creature in Chinese mythology.

Function Integration. In the CTP 3.0 battery, the internal crossbeam, 
liquid-cooling plate and thermal pad have been integrated into a 
multifunctional elastic interlayer. It also features built-in micron bridges 
inside the interlayer, which flexibly accommodate the changes inside the cell, 
improving the battery reliability throughout its full life cycle. The 
integrated energy unit, which is 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. 

Reshaping system structure. Powered by its precise computing and AI simulation 
capabilities, CATL explores the boundaries of battery design involving the 
battery's full life cycle application scenarios. The ingenious bottom sharing 
design allows the smart arrangement of various components including structural 
protection, high-voltage connection and a protective vent for thermal runaway, 
further increasing the battery capacity by 6%. Meanwhile, the CTP 3.0 battery 
satisfies the criteria of the battery safety tests required by national 
standards such as the bollard test.

Disruptive Water Cooling Design . By placing liquid cooling functional parts 
between adjacent cells, the trailblazing large-surface cell cooling technology 
increases the heat transfer area by four times, cuts thermal control time in 
half, and supports a hot start in 5 minutes and fast charging in 10 minutes. It 
enables the cell to cool down rapidly in extreme circumstances, effectively 
preventing abnormal thermal conduction among cells. Moreover, it has achieved 
thermal stability and thermal safety for all chemical systems, making it 
compatible with materials with higher energy density.

From the material, cell to system structure, the systematic engineering mindset 
runs through the whole chain of research and development in CATL. Supported by 
the above-mentioned technological innovations, the CTP 3.0 battery can increase 
the energy density to 255Wh/kg for ternary battery systems, and 160Wh/kg for 
LFP battery systems. With the same chemical system and the same pack size, it 
can deliver 13% more power than the 4680 battery, accomplishing an all-round 
improvement in range, fast-charging, safety, service life, efficiency and 
low-temperature performance.

The CTP 3.0 batteries, or Qilin, are expected to be mass produced and come on 
the market in 2023. From simulated computing in the micro world to artful 
streamlining inside the battery structure, CATL remains focused on 
technological ingenuity and independent innovation, aiming to promote the 
overtaking of fossil fuel vehicles by electric ones.
