I wonder more and more where the massive battery production increase will get their cobalt from. Production in the coming 5 years will be multiplied, maybe even towards a different magnitude! As such, the cobalt and lithium demand will scale in the same fold. Lithium is relatively widespread (compared to cobalt), so while it gets harder to get lithium (and more expensive), it will not be impossible.
Cobalt however is quite a different story. What are the producers planning to do? Dig up half Congo?
