Clickbait title. Goddard's law applies to the implied question. Relevant bits...
The theoretical energy density limit for lithium-air systems is 12,000 Wh/kg. Gasoline sits at roughly 13,000 Wh/kg, and modern laboratory battery prototypes have reached more than 1,200 Wh/kg. That last number is four times higher than the 250 to 270 Wh/kg capacity found in mainstream electric cars today.
It's a pretty interesting tech, regardless of CATL.
Do you have links for these claims?
Not saying I don't believe it, I just want to read about it myself.
Btw. I think you used sea mile as reference when converting miles into kilomeres. 1 million milles would be more like 1.6 million kilometres.
No, they batteries last longer when not in the US or UK. Something about the people there cause some batteries to kill themselves prematurely which skews the numbers a little bit.
Not sure about the mailage of the voyager probes (wikipedia states a distance from earth of 16billion mi) an they also have batteries with them. Does this count?🤔
After 2 million kilometers (1.25 million miles), CATL’s EV batteries retained about 400 km (250 mi) of range. Competitor cells, on the other hand, retained considerably less, at around 350 km (218 mi) and less.
The data is based on 12 electric vehicles, 100 sample batteries, and real-world applications across four major cities in China. You can see in the chart from Morgan Stanley Research that Models 11 and 12, which use CATL batteries, exhibit considerably slower degradation than the other suppliers.

Prove it or shut up.
CATL has in the past claimed, unsuccessfully:
CATL is a shit company. Period.

To add, modern engines can utilise about 3000 Wh/kg from gasoline

A one million mile battery is easy... The sun is a battery if you think about it wrong.

What leads you to believe that CATL has been unsuccessful at achieving a 1 million mile battery?

Is energy density based on energy per volume or per mass?
EndlessNightmare@reddthat.com · 8 pts · 86d
Energy density = energy per volume
Specific energy = energy per mass

why does the thumbnail show Wh/kg
kg/W?party_planet@lemmy.world · 1 pts · 86d
watts = joules per second, so watts x hours is a measure of energy

Is it an iron-feathers battery?

"What weighs more, a Kg of iron or a Kg of feathers?"
