Mostly Australian mines. There's no projected shortage that I have ever heard of. There's plenty of Lithium in them there hills.
Good to hear!
Reason why I thought there was a shortage was because there was a major push to recover Li from old phones a few years back. I have 4-5 old unused phones lying around my house. (Mostly because there's old text messages in them that I'm hoarding.) I presume it's the same for others. And I was wondering whether there's enough Li for new phones.
