As an American I thought it would be much worse. 75% or more. We have been shitty neighbors. Seriously, threats, tariffs, insults, etc.

We already agreed to that when Ukraine gave up the nucs. Look what that did, nothing. Why would they try again?

Two important parts of a battery are how much energy it can store in a certain space and how much it weighs. If it is bigger and holds the same amount of energy that might be ok for a non mobile storage if it costs less, like a house. If it weighs more for a certain energy that wouldn’t be useful for cars and mobile things but might be ok for small things where the weight is negligible anyway. For cars you want a small energy dense battery that is light as possible
