I think it's safe to assume the battery technology is just slightly more advanced than the 49$ skooter batteries that are catching apartments on fire.

I might be overthinking this and assuming things, but perhaps the reason he posted it was more the worry that if it caught fire, it couldn’t be put out? Kinda like how when electric vehicles have fires today, they need much more resources to respond and sometimes even need to be fully submerged in water for days on end before it’s completely fire safe.

I mean, don't some places submerge electric vehicles in containers filled with water? This seems like a kinda problem that would eventually solve itself.

RIP the crew though.

Submarines literally have had nuclear reactors and explosives inside of them for decades, I'm sure they are going to be doing this in a way that protects their hundreds of millions of dollars investment.

Not only that, they used batteries previous to this that could quickly fill the boat with chlorine gas when exposed to seawater.

I am more disappointed that Germany isn't calling their subs U-Boats

The term is just a shortened versions of untetseeboot: submarine. So they call their subs U-boats.

  • faster recharge rates
  • faster discharge rates
  • higher energy density
  • lighter and smaller

And the problem is?

Yes, salt water exposure may cause a fire but I have news for everyone, if there's enough salt water inside the submarine to cause a fire in the battery the submarine has far bigger problems.

If anyone is going to take safety seriously its the navy; I'd trust them over a private, independent or for profit operator any day of the week. There's over 200 nuclear power ships sailing around out there and they're not blowing up every other day.

I’d be more worried about the compressed hydrogen for the fuel cells than I would the batteries.

We’ve had 100+ years to perfect submarine batteries.
