Re:The race to grab all the UK’s lithium before it’s too late

I'd check your napkin ;)
5% of the world electricity usage divided by wholesale electricity cost, divided by world lithium production in grams ->
(5% * 2.5e+16 Wh X $30/1e+6 Wh) / 8.2e+10 g = $0.45 per gram (or 15kWh per gram of lithium)
The takeaway is that energy is currently unreasonably cheap.
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.
