CATL $3750 (+5,79%) claims to have reached 1.8 million kilometers under certain conditions - 6 times the current industry standard.
CATL promises an electric car battery with a record-breaking service life in a new video. The Chinese manufacturer claims that its 5C batteries can last a million kilometers even with constant fast charging.

5C means that the battery can be fully charged in around 12 minutes. This puts it in the "ultra-fast charging" category.
》80 percent capacity after 1,400 charging cycles《
Even under extreme conditions of 60 degrees Celsius - CATL is talking about summer temperatures in Dubai - the battery should still hold 80 percent capacity after 1,400 charging cycles. This corresponds to a total of around 840,000 kilometers.
Under moderate conditions, even 3,000 charging cycles should be possible before the battery falls below 80 percent of its original capacity. This corresponds to 1.8 million kilometers - 6 times the current industry standard, according to Car News China.
》Improvements to the battery《
In the promotional video, CATL justifies the progress with 3 innovations:
Firstly, a dense, uniform coating has been applied to the cathode. This prevents it from being damaged by intensive use.
Secondly, an additive has been added to the electrolyte that can repair microcracks and thus reduce the loss of lithium.
And thirdly, a temperature-sensitive coating on the separator layer between the battery poles slows down the migration of ions when temperatures rise in places.
This helps the battery to self-regulate and reduces the risk of a fatal "thermal runaway", in which the battery burns down explosively.
CATL is not yet sure when the new battery technology will go into mass production or in which vehicles it will be found. It will probably first be found in the high-end sector before it is used more widely.
