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.

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.
