At first I was as confused about lithium like many. This might help with Kwh and Gwh.

1 kwh= around .95kg LCE A tesla 75kwh use 71.25kg LCE.
1000kg carbonate = $14000 or $14/kg.
71.25 × 14= $997.5 of carbonate for each tesla.

1000Kwh= 1Mwh
1000Mwh= 1Gwh.

2 × 50GWH(100GWH) = the world total battery grade supply of 2018.

1450GWH battery factories are planned to be built by 2028. Or 14.5 times the current world supply.
1450% ÷10 years =145% increase needed each year just to meet demand. 100% increase is not even possible.

A disconnect between demand and supply is an understatement.
Anyone without supply is out of the game.
