On June 23, CATL introduced Qilin, the 3rd era of its CTP (cell-to-pack) generation. With a record-breaking quantity usage potency of 72% and an power density of as much as 255 Wh/kg, it achieves the best integration stage international thus far, able to turning in a variety of over 1,000 km in a breeze.

Specializing in the very nature of electrochemistry, CATL continues its enterprise to push past the bounds of inventions in machine construction. In 2019, CATL introduced the sector’s first module-less battery pack CTP, taking the lead achieve a quantity usage potency of over 50%. Along side general breakthroughs within the core procedure, set of rules and fabrics, CATL redefines battery construction design with “Qilin,” which is called after a mythical creature in Chinese language mythology.

Serve as Integration. Within the CTP 3.0 battery, the inner crossbeam, liquid-cooling plate and thermal pad had been built-in right into a multifunctional elastic interlayer. It additionally options integrated micron bridges throughout the interlayer, which flexibly accommodate the adjustments throughout the mobile, making improvements to the battery reliability all the way through its complete lifestyles cycle. The built-in power unit, which consists of the mobile and the multifunctional elastic interlayer, builds a extra strong load bearing construction perpendicular to the using path, thus improving the surprise and vibration resistance of the battery pack.  

Reshaping machine construction. Powered by way of its exact computing and AI simulation functions, CATL explores the bounds of battery design involving the battery’s complete lifestyles cycle utility situations. The creative backside sharing design lets in the good association of quite a lot of parts together with structural coverage, high-voltage connection and a protecting vent for thermal runaway, additional expanding the battery capability by way of 6%. In the meantime, the CTP 3.0 battery satisfies the factors of the battery protection exams required by way of nationwide requirements such because the bollard check.

Disruptive Water Cooling Design. Via striking liquid cooling purposeful portions between adjoining cells, the trailblazing large-surface mobile cooling generation will increase the warmth switch house by way of 4 occasions, cuts thermal keep an eye on time in part, and helps a scorching get started in 5 mins and rapid charging in 10 mins. It permits the mobile to chill down unexpectedly in excessive instances, successfully combating atypical thermal conduction amongst cells. Additionally, it has completed thermal steadiness and thermal protection for all chemical programs, making it suitable with fabrics with upper power density.

From the fabric, mobile to machine construction, the systematic engineering mindset runs thru the entire chain of study and building in CATL. Supported by way of the above-mentioned technological inventions, the CTP 3.0 battery can building up the power density to 255Wh/kg for ternary battery programs, and 160Wh/kg for LFP battery programs. With the similar chemical machine and the similar pack measurement, it might probably ship 13% extra energy than the 4680 battery, carrying out an all-round development in vary, fast-charging, protection, carrier lifestyles, potency 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.
