Prove it or shut up.

CATL has in the past claimed, unsuccessfully:

  • $10 per kilowatt-hour batteries
  • 1-Million-Mile (1.8-million-kilometer) batteries
  • that CATL doesn't steal end user data without notice
  • that CATL doesn't use forced labor
  • that CATL doesn't steal international patents

CATL is a shit company. Period.

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.

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

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.

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

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?🤔
