Is anyone able to clarify what constitutes LCE exactly? Not having much luck on google, although might be misinterpreting some concepts.

You mentioned earlier that "3,595GWh, will require 2.9 million tons LCE per year by 2030". Trying to get my head around supply and demand here.

At 10mtpa, AVZ will produce 300k PLS and (or?) 100k LiOH? Does this mean that AVZ would contribute 300-400k LCE to the industry a year. Or is LCE a further post processing step.
