CATL introduced its third-generation CTP battery know-how


The world’s greatest battery maker, CATL, introduced that its third-generation CTP (cell-to-pack) battery know-how is prepared for mass manufacturing and the official launch is anticipated in April.


Monetary Related Press on March 26, Wu Kai, chief scientist of CATL, mentioned on the China Electrical Car 100 Discussion board that CATL has launched the third-generation CTP know-how by steady technical iteration, which is known as “Kirin battery” internally.

Weight, vitality density and volumetric vitality density proceed to guide the business on the highest degree. Beneath the identical chemical system and the identical battery pack dimension, the facility of the Kirin battery pack might be elevated by 13% in comparison with the 4680 system. The reporter was knowledgeable that this battery can be formally launched in April this 12 months. (Reporter Liu Yang from Monetary Related Press)


What’s nice about CTP battery packs, is that with out modules and extreme cabling, they’re simpler, quicker and cheaper to assemble. The much less passive materials the higher, since what actually issues is the lively materials (battery cells) that truly shops vitality. CTP know-how is barely potential to make use of with protected battery cells, that don’t simply burn or explode when broken.


Let’s see the vitality density specs of this third era battery pack know-how from CATL.


LFP model (LiFePO4 is cobalt-free)

  • Gravimetric vitality density: 160 Wh/kg
  • Volumetric vitality density: 290 Wh/L


NCM model (incorporates cobalt)

  • Gravimetric vitality density: 250 Wh/kg
  • Volumetric vitality density: 450 Wh/L


Proper now the most well-liked CTP know-how with cobalt-free battery cells is the BYD Blade Battery – that began with 140 Wh/kg, however already reached 150 Wh/kg within the long-range model of the BYD Yuan Plus.

Anyway, if the Tesla Mannequin 3 MIC (Made in China) will get its LFP battery packs upgraded to this new know-how, the vitality density may enhance by 28 % – from 125 to 160 Wh/kg. Since CATL is at the moment the LFP battery cell provider of Tesla, this might occur quickly.

LFP batteries are an awesome step ahead to make electrical autos mainstream, however now I need to see a CTP battery pack made with sodium-ion cells, as a result of that’s when it’ll be potential to switch the just about 70 million ICE (Inner Combustion Engine) vehicles which are made globally yearly with electrical vehicles.
