Where they stand, two measures at a time

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.

Nominal capacity × Cost of stored energy

20.70 Nominal capacity · kWh 6.90

0.28 Cost of stored energy · €/kWh 0.32

On Cost of stored energy, further left is better; on Nominal capacity, higher up. The coloured corner, “best zone”, is where both measures are good.

Filled in is the 1 product that no other beats on both measures. It is not «the best»: it is the one nobody dominates.

Striped, paler points have at least one of the two measures without a verified source.

27 sheets are missing, because they do not state both measures.
