RE:Lithium2Moon..Diabase...Battery metals..Lithium-NiobiumAs far as future supply shortages for battery marterials Lithium is king IMO. Graphite will see a large supply shortage as well just not to the same scale. The only risk to graphite is technological advancement in solid state batteries which would remove the anode and almost eliminate the need for graphite in batteries. It all depends on your timeline. Personally, I think companies are pooring too much money into the current cell production supply chain to abandon it in 10 years as they will start operating in 3. So natural graphite is likley a reasonable bet. But you never know. DYOR
