A single-number ranking hides what is being optimised. Here there are two axes at a time, and the question «which are the best» is answered by those nobody beats on both measures.
On Cost per kWh, further left is better; on Nominal capacity, higher up. The coloured corner, “best zone”, is where both measures are good.
Filled in are the 2 products that no other beats on both measures. They are not «the best»: they are the ones nobody dominates.
One sheet is missing, because it does not state both measures.

On Energy density, further right is better; on Continuous output, higher up. The coloured corner, “best zone”, is where both measures are good.
Filled in are the 3 products that no other beats on both measures. They are not «the best»: they are the ones nobody dominates.
Striped, paler points have at least one of the two measures without a verified source.
5 sheets are missing, because they do not state both measures.
