The Lithium guys are going to talk down Cobalt, as they want you to invest in their thing of course. The reality is you should be in both, and you can choose which one you want to be heavier into, or take a balanced approach. If you're looking at it from a battery point of view, you need to weight up the chemistry, percentages and the processing and final cost of each. Final cost of each can be determined by comparing cost in USD/per pound and converting back to AUD/kg, but that doesn't tell you processing/mining costs of course. I suspect Cobalt is the cheaper production process as it is performed via hydrological methods, like acid leaching etc.
