There's plenty of lithium, but what about everything else...

While I always see debate on if there is enough lithium to support all of the new Li-ion battery initiatives, I see very little debate on other material constraints that might occur. Li-ion cells contain large amounts of stainless steel, nickel, aluminum, and copper. When looking at the overall percentages of each of these materials, they are far greater than any amount of lithium present. At the pack-level (full battery), this problem will be exacerbated from all of the tabbing, wiring, and BMS component raw material needs. I wonder if anyone has considered this being the major bottle-neck?
