All of that can be fixed. But one thing that can’t be done is improve energy density of Lithium batteries. Simply put they are too heavy for the amount energy they store, have issues in cold weather, prone to mechanical failures, etc. Even if high pressure tanks are more expensive, we could start with lower pressure ones and work our way up as technology improves. Simply put it scales better.
It also has the disadvantage of being harder to fill and harder to contain (not dangerous, exactly, but hydrogen tanks generally leak.)
