Ok, you were clear this time.
Indeed we need to confirm with Maria Helena Braga if the lower cost they speak about it's lower per cell unity, or lower per KWH.
Like I said, even if the price per each cell of a given size (like 18650 size cells) it's the same for conventional Li-ION cell, you would still have at least 3x (and up to 10x) less expensive cost per Kwh.
But I presume it's the cost per cell, since the materials are lower cost (no cobalt) and the manufacture process have no great mystery (no one I found) and can be made even from sodium.
But another doubt I have it's about energy density per weight and energy density per liter, how both measures of density compares from their new batteries, if we compare the lithium metal battery to the sodium metal battery versions they created.
