    "I get about 2.1 million tonnes of chemical grade spodumene concentrate capacity in 2019, accepting all the yellow in the above btw."

    Firstly, thanks for your answer. If you think all this capacity is really going to come on line in 2019 I think there might be a problem based on my base case assumption that Tesla retains its 14% world wide market share in 2019.

    With 2 million EV sales in 2018 and Tesla's recent stated market guidance of delivering 400k EVs in 2019, if you use my assumption for the base case (ie Tesla retain 14% worldwide market share of EV sales in 2019) then using your metric of 375,000 dmt of 6% spod for 1 million EVs/annum, the EV market in 2019 will reach

    (100/14) x 400k = 2857142 = ~2.86 million cars in 2019 (base case)

    which would require 2.86 x 375,000dmt spod = 1,072,500 dmt of spod as per my previous calculation on the PLS thread.

    This is approximately half of that 2.1 million tonnes of capacity from that chart. That capacity doesn't include battery grade brine production and small scale production but at the same time my base case calculation doesn't factor in Tesla losing market share (ie expansion of non-Tesla EV car sales in 2019) or demand for battery grade lithium for non-car use.

    Nevertheless if you believe that chart actually represents actual realisable capacity for 2019, it leave a big gap between supply and demand with supply based on cars alone exceeding demand (base case) by 2,100,000 dmt - 1,072,500 dmt = 1,027, 500 dmt excess supply in 2019.

    To reiterate assumptions here are.

    1) 2 million EV sales worldwide in 2018
    2) Tesla retain their WW market share of 14%
    3) Tesla 2019 guidnace of 400,000 EV car deliveries in 2019 and
    4) Scarpa's calculation of tonnes of battery grade 6% spod for the production of 1 million cars/annum (50kg of lithium per car) = 375,000 dmt for 1 million cars
    5) Base case supply doesn't include battery grade brine production and aggregate small scale production
    6) Base case demand is for EV's only (2.86 million units delivered world wide in 2019 calculated using assumptions 1 to 3 above) does not include non-EV battery grade spod demand for other Lithium ion battery applictions.
