My back of the napkin calculations say it's impossible. The world produces around 25 000 TWh of electricity and 82 000 tonnes of lithium annually. EDIT: wrong

My back of the napkin calculations say it's impossible. The world produces around 25 000 TWh of electricity and 82 000 tonnes of lithium annually. EDIT: wrongly assumed that 100% of the world's electricity is used for lithium mining. Correct version below: For this to be true at $30/MWh one gram of lithium would need to cost ~$0.45, so a kWh of li-ion batteries would clock in at around $90 just for the lithium. Li-ion batteries are already bought and sold for less than that.
