Ann: Goulamina Resource increased by 33.8 Mt to 142.3 Mt, page-198

I am well aware of that @PieChart. I believe his estimation is on the money especially considering Li has an atomic weight of 3 and Na is 11.

I'll leave it up to you to decide why CATL convieniently decided to not disclose that information publicly when every other lithium ion battery manufacturer including CATL has disclosed volumetric density of their batteries for LFP and NCM etc. Add to that they have made several efforts to drive the price of Li down lately.
