The transition from coal to oil in transport a hundred years ago was tough and bloody. The coming transition from oil to electric is of course being resisted by a monolith oligarchy today. Electric is plainly too expensive right now, but it is slowly getting more affordable.
Once electric proves itself to be the way forward (and importantly achieves COST PARITY with the oil fueled product) it will win this arm wrestle.
Lots of building blocks developing as we've seen. I firmly believe ALL the major car companies will have affordable, mainstream product in the next 3 to 5 years, so thus I don't see lithium as a short term game.
The build will IMHO be steady and consistent, but once equilibrium is reached with oil costings, the surge and growth of electric (and thus lithium demand) will be exponential.
