Let‘s do the napkin math:
- Biggest EV batteries are about a ton
- Let‘s even assume they’re all lithium
- Lithium from seawater can be produced everywhere worldwide at about 5$ per kilo [1]
- That‘s 5k for a powerful battery lasting a decade.
- Seawater is as abundand as it gets.
-> Okay, this is really pure BS, and the only question remaining is which agenda is behind it

- quonn 4y agoIt seems that a typical battery might only need 5-75 kg Lithium. So that would then be < $400 if your computation is correct. So even better. Even if this cost would be on top of existing costs this would still be not prohibitively expensive.

- lm28469 4y agoThat's a lot of "would" and "may" in the article. Battery and lithium breakthrough articles are a dime a dozen
- Incipient 4y agoYou misread that. It's $5 of electricity. Nothing about the membrane, how long it lasts, any of the construction and maintenance costs, etc. And that's if that quote on the cost of electricity is remotely correct too. And unless they have any of these facilities under construction, they're not going to contribute to supply issues in the next 3-5 years.
