CATL Declares Third-Technology CTP Batteries


CATL, the world’s largest lithium-ion EV battery producer, introduced the third technology of its cell-to-pack CTP battery system, internally referred to as Kirin or Qilin.

The CTP is a system that makes use of prismatic battery cells which might be mixed into packs with out modules to scale back complexity, weight, area and value.

The most recent CTP 3.0 will probably be out there in two variations, for LFP and NCM battery cell chemistries, providing fairly aggressive vitality density:

  • LFP:
    ≥ 160 Wh/kg
    ≥ 290 Wh/l
  • NCM:
    ≥ 250 Wh/kg
    ≥ 450 Wh/l

CATL says even that the Kirin battery can obtain 13% greater “energy” on the pack stage than the “4680 system,” assuming the identical cell chemistry and pack measurement. There isn’t any phrase about Tesla, nevertheless it clearly factors at Tesla’s 4680-type cylindrical battery cells. With out viewing full specs of each varieties, we aren’t ready to judge the variations.

In accordance with the Chinese language firm, CTP 3.0 is prepared for mass manufacturing, and its official market launch is anticipated in April.

One of many photos presents additionally a modular CTP system, which, relying on the car sort, can use 1, 2 or 3 CTP packs:

Wu Kai, CATL’s chief scientist, hinted additionally that in 2023 we are going to see mass manufacturing methods that enable 1,000 km (621 miles) of vary on a single cost.

For reference, the BYD Blade Battery (LFP and CTP) was estimated at 140-150 Wh/kg within the case of the BYD Yuan mannequin. factors out that if Tesla would use the CATL’s new batteries within the Made-in-China (MIC) Mannequin 3/Mannequin Y entry-level variations (as an alternative of its present CATL’s LFP cells and personal battery pack) it may noticeably enhance the vary – by as a lot as 28%, assuming enchancment from 125 to 160 Wh/kg.

We do not understand how correct the estimations of potential positive factors are, however for positive there’s a probability for some enhancements, which might translate into a better vary.
