Thank you! So at the current lithium carbonate price of $80/kg, the processed lithium in a Tesla probably costs $1k-2k? If so, even a 50% drop in lithium prices would make a Tesla only 1k less to build.
Maybe less than that. @mongo, can you add anything to this inquiry?
Here is another useful link

850 grams Li-carbonate per kWh battery storage
The Model Y LR is ~ 82 kWh
Current spot price for Li-Carbonate is 437 Yuan per Kg,
So Li component in Model Y LR is 437*87 Yuan = $5309 USD
In spot prices. I have no idea how much Tesla pays
At 100% utilization, a 75kWh pack needs 5kg of Lithium.
Concentrated spodumene is 7% Li2O. (I screwed up the
Li2O is 46.5% Li by mass.
5 kg/0.465/0.07 = 154kg of high proof spodumene.
$7,181 per tonne
154*7.181= $1,106
Lithium carbonate is Li2CO3, 18.8% lithium by mass
5 kg/.188 = 26.6kg * 437 = 11,630 yuan = $1,700 USD
But a little more than that due to cell inefficiencies.
