raw material costs - the researchers calculate under $9 per kilowatt-hour (from the article). Cycles seem to be related to how fast you want to charge/discharge it. > If the cell was discharged over two hours and charged in just six minutes, it still had a charge capacity per weight that was 25 percent higher than lithium-ion batteries and retained roughly 80 percent of that capacity after 500 cycles—well beyond what you'd see with most lithium chemistries.

This loss is not realistic since most EV don't charge to 100% or discharge to 0%, where the low cycle count comes into play. Many will only charge to 80% charge capacity, but display 100% "range capacity", to maximize longevity, since most damage happens > 75%. But, this also means EV's have even poorer energy density. > the researchers calculate under $9 per kilowatt-hour Raw material isn't all that useful, without knowing the cost of a full cell. Enough raw material, for a handful of diamonds, can be found in your nearest dead shrub.
