Yes you are right, but it is likely that EV growth involves two separate trajectories for EV batteries, one for the mid to luxury range and another for the smaller range EVs. The latter would be inclined towards sodium-ion batteries in the years ahead for low cost production. But it is also the smaller EV cars that enjoy stronger growth, so when we talk about EV growth, a larger portion would be attributable to smaller cars that eventually go to embrace non-lithium batteries. The cheapness of lithium would certainly slowdown that migration, but the presence of alternate battery technology does cap the extent of the rise of lithium price.
