China launches world’s largest electric container ship with 50 MWh battery

Using standard container sizes as battery modules is kind of genius. That way they can be swapped out when they get older and newer technology comes along, they could even be swapped between ships.

I expect they are using LFP which doesn't do that.

Fortunately energy density is not a concern with boats.

These batteries are likely far more complex in packaging, design, and thermal management that any consumer electronic cell. They'll likely "fail safely" if/when they do fail.

Good news, it’s surrounded by water! Bad news, it’s surrounded by water. 😡
